"Ernesto"
Updated: 2024 October 18, evening
Sunday I got home and it had been almost a week since I last looked at GeyserTimes. On the latest Grand entry, there was a comment that the entrant said that they didn't know what Grand code to use since they started together. User34 replied to the effect that "ties go to Grand." I also posted a comment noting that User34 was correct, that the code corresponds to the difference in start times, with "T" being negative, while "G" is non-negative, and that zero is not negative.
This was the second time this year that i had to make that clarification to someone, and it occurred to me that I should write up and document exactly what and how a Grand eruption gets recorded, or at least how I do it.
Perhaps it was the residue of the anesthetics and other drugs in my system, but I quickly prepared an entry that covered most of the important points. Best of all, when I re-read it a couple of days later, it still made sense. I noticed a few things I missed, but added them and finally posted it a few days ago.
During the last week it became obvious that a Klaque of Kewl Kidz were posting to GeyserTimes, especially in note entries. These consisted of jargon and jibberish and were obviously intended to be cryptic and useless as descriptions or of any help to others. But since the owners of GeyserTimes seem to tolerate that sort of abuse, I try to ignore it.
Then this morning KCooper posted this note, which got flagged by Udo
"Ernesto is somewhat beefy but inconsistent (strong and variable)".
At first I was tempted to double flag it, but decided I really shouldn't, since I don't like it when others do that. But when I looked again a few hours later, the flag was still there, with an expanded note attempting to explain away the jargon being used. There was also a smarmy, insulting comment added by SantaFe108.
That's when I decided to have a little fun. I opened a flagentry , and wrote up the following:
"if you flag this one might aswell [sic] flag most CCI notes on here, and many other features." - SantaFe108
Good idea. Maybe a general cleanup and reduction of noise would be appropriate.
If notes are not clear as to what they are describing, then they are inappropriate and should be removed. What terms mean should not be defined in the comments as is being done here. Even then there is still no objective description as to what constitutes "weak" vs. "withering" or all the other gibberish.
As it is too many of these notes and comments are noise that only serve to inflate the egos of the persons reporting them, or farming to add to their already inflated GeyserGamer score.
Then I hit the "submit" button and waited to see what would happen next.
It took a few hours, but at some point people figured out what had happened. Now this evening, I see everything but my lock comment has been restored. But I've also heard it got the attention of a few people, too.
This behavior is too often typical of GeyserTimes, where jerk-like behavior is tolerated to the point that it becomes overwhelming and a bit repulsive. Especially from GeyserGamers who think their subjective opinions are of lasting value, or who use the database as their personal logbook.
Update 2024 Oct 18 evening
Well, "Ernesto" made another overnight appearance. It appears that KCooper has decided that since his inappropriate notes were restored yesterday by the owners of GeyserTimes, he and the other Kewl Kidz have unlimited license to be jerks, and engaged in a little victory celebration.
This whole episode has given me a greater appreciation and understanding as to why the NPS prohibits the entry of any electronic data into GeyserTimes. And re-inforces my decision to limit my participation. Until the owners of GeyserTimes clean up their act, it's only going to get worse.

Timing and Recording a Grand Eruption
When I first started watching geysers in the early 1980's, all that was recorded for Grand in the green logbooks was the start time and the number of bursts. As I started to watch Grand more closely, I thought that there were several other items of interest that could be easily recorded, and that didn't require precise timing.
If you record start times to the second, and you make a point of getting both Grand and Turban, you will then have a good idea of the interval of time between the two geyser starts. Noting such starts to only the minute is just an exercise in generating noise, as you won't see enough eruptions for statistics to sort those starts into enough bins that any sort of analysis will be useful. (The same goes for recording Vent starts, other than to definitely say that Vent started. Since I know of only three eruptions of Grand in a close to half century where Vent did not start until near the end of Grand, it would be better to loudly note that Vent did something unusual, not that it behaved normally.)
But most people don't need to record times to the second. But knowing which geyser started the eruption could still be statistically interesting, so I came up with the "T" and "G" prefix. Technically, the time between the start of Turban and the start of Grand determines which to use. If the number is negative, then that is a Turban Start. If non-negative, it's a Grand Start. Since zero is a non-negative number, this means that Grand gets the ties.
Since I started video recording Grand starts, I've noticed that I'm not always accurate with the exact second that a geyser start. Sometimes off by a couple of seconds, which can add when events are spaced closely together. But getting which geyser actually initiated the eruption is reliable, so I'll leave it to someone else to go through all my posted videos and come up with more accurate start times. So G vs. T is still a good measure.
The other item of interest was how the eruption ended, and for that, we have Continue and Quit. What constitutes a Continue is pretty easy to define-- it's when Vent and Turban don't stop. (And I have never seen just one quit and the other continue, but I never expected to see a second Grand burst before Vent starting…)
As a gross measure, Quit is also obvious, but timing it can be tricky, as which geyser quits first can vary a fair amount. (I've got video records if anyone wants to look at them…) Usually it means that it is the time when I notice that Vent has died down and I don't see any activity from Turban.
If you want to wait around from six to 25 minutes, you can catch the Restart time after a Quit eruption. The restart time is the time of the second surge coming from the empty Turban crater. The first surge can be small enough to be missed, but starting with the second Turban activity is becomes obvious and nearly continuous.
Back in the 1980s there was a lot more variation in Grand's burst activity, with multiple bursts expected. Sometime when we got only a Two Burst Eruption (calling it a "Double" means you are displaying your ignorance of the terminology), we noticed that that second burst lasted a long time. From the little bit of data I'd collected, I set an arbitrary limit of 75 seconds. Any burst lasting that long, or longer, was a "Long" burst. Since it was the start of using computers to record data, I decided to use the "*" character to denote that. Once again, it was one of those things that didn't need timing to the second to determine. (Maybe a 70 second burst got recorded as a long, or an 80 didn't get recorded, but that's not significant.)
Then of course we got a Long Burst on the third burst (if I remember correctly, it was also a Four Burst Eruption). So I used the "#" character to denote that. (If a long Fourth had ever happened some character would've had to volunteer to be used.) Back in May earlier this year several of us got to see a Grand eruption with both a Long Second and a Long Third burst.
Once Grand's pool drains it's still possible for there to be more bursts. These are Afterbursts, and can occur several minutes after the previous burst ends, as long as Vent & Turban continue. Normally it can take well over ten minutes for splashing from Grand's vent to start, but afterbursts start with splashing almost immediately. This splashing builds in intensity, and at some point becomes continuous with actual bursting and a full pool. The burst count of this activity is recorded separate from the main eruption burst total, using a "+" to denote the afterburst. Back in the early 1980s there were several Grand eruptions with a second afterburst observed.
Suzanne Strasser first noted the "Two Turban Delay" in the late 1970s. It was not unusual for Grand's pool to fill and then not have Turban erupt at its usual rhythm of 18-20 minutes. In 1983, we were getting these delays just about every Grand interval, and the delay wasn't for two Turban Eruption intervals but for five or more. So it seemed worthwhile to note when these happened, and how long the recovery took.
Since Grand had been observed to erupt as much as thirty minutes after the previous Turban eruption, came up with the idea of "Delay zero" being the Turban eruption following the Delay. If Grand erupted, that was a relief. If not, then the count began.
Every subsequent Turban eruption got the Delay number incremented by one, and it wasn't unknown for it to reach double digits (usually after midnight). But we also found that there could be multiple Turban Delay Intervals. Did that matter? Decided that it did, and to record that, we would restart the count. It seemed that the pattern of D3/D2 was fairly common, where if Grand tried to start on the third interval and failed, it would finally erupt two more Turban Eruption intervals later.
Once again came up with an arbitrary time interval definition. Turban intervals up to 23 minute long seemed to occur enough that they weren't noteworthy. But by 25 minutes, one could tell that Grand wasn't going to erupt and most delays were longer. And an arbitrary 25 minutes is easy to remember.
I noticed in the early 1980s that often Vent would overflow around the time that Turban started just before a Grand eruption. Because of its location, the start of overflow could be hard to see and was frequently overlooked. Then there were times that Vent would overflow, especially during a Turban delay interval, and Grand wouldn't erupt. So started noting that with a "V" delay code.
The term "boop" came from Bob Fittro, one of the gazers who was around during the late 1980's and early '90s. He was one of those people for whom "it's after 5 o'clock somewhere." So there's a small group of us sitting out on the old wooden boardwalk benches at Grand when he fumbles his drink and spills some. The immediate comment was, "my drink booped". It was around the time when the large boils on Grand that did not result in an eruption were becoming annoyingly noticeable. Almost immediately we started using that term, "boop" for one of those boils. It's quite possible that on the next Turban eruption that evening, that's what happened, hence the quick application of the term.
As with the Vent overflow, it was easy to note a Boop Delay and use a "B" as the delay code.
The Grand eruption itself doesn't start until Grand starts jetting. Some of those boop/boils can reach several meters high (I have a few on video) and come well before the actual start. It still amuses me when some newcomer, upon seeing such a boil, immediately announces over the radio that Grand has started. Fortunately for them, most of the time a subsequent boop will result in the eruption, so then don't need to retract their announcements. But as with "Waves on Grand", make that announcement at your own peril and be prepared to issue a correction.
A "Boop Delay" or "Vent Delay" doesn't need to last the full 25 minutes of a Turban Delay. The fact that Grand made an attempt (which are what the vent overflows and boops are) was good enough.
There are other times that could be recorded as part of the whole Grand eruption cycle. The start of overflow from Grand is one. It's best seen on a warm afternoon where the terraces dry out. As the pool rises, suddenly a patch of sinter on the front left side starts to change color as water starts to flow over it. Within a few minutes, water is visibly trickling out over a broad front, so it's not really necessary to get an exact timing. But when I've measured it over the years, the time has been fairly consistent, around 4h20 to 4h10, despite all the variations in Grand's eruption interval. It's only when Rift erupts that the first overflow time can be delayed, sometimes for several hours.
Noting the activity of all the other features might be useful. Until this year, the sequence of event leading to the start of Rift erupting was fairly well known and consistent, with West Triplet and Percolator playing their parts. This past year, however, no one ever saw the start of Rift. Other than the West Triplet runoff being dry, which would indicate no eruption there.

Observations for 2024 September 09
Before sunrise I was over by Castle and started to feel droplets. Despite the weather forecast of clear, the clouds overhead were more than just keeping it dark. Didn't have a long wait for the Grand eruption, and once again it was a short two burst eruption that seems to have made no attempt at a third burst. At least Vent & Turban didn't quit.

With time to kill, went over to Geyser Hill as it had been sixteen hours since the previous Beehive eruption. Didn't have a chance to start reading a book when the Indicator started. This was also a relatively short Indicator, with a duration under 20 minutes.
It was also windy up there, and I thought at times I could smell the breakfast odors coming from the Lower Store, as it would have been directly upwind. With is more interesting as during the Beehive eruption they had a fire alarm over there go off.
Later it was another short wait for another One Burst Grand Eruption. The wind had not improved and the smoke seemed stronger by then. After the eruption West Triplet came up to overflow. It had some heavy convection but no thumps or splashes.

Mid-afternoon was the time to check out Fountain, based on its earlier activity. Arrived just in time to see the start, a 4-1/2 hour interval, along with a couple of Morning's Thief eruptions.
At sunset walked up to a Turban Delay Interval, but fortunately, we got the One Burst Eruption instead of a couple of hours of a delay. The eruption itself lasted 12-1/2 minutes, with Vent & Turban quitting within seconds of Grand's end.
2024-Sep-09:19:41:56 D0/G1Q 19:41:56 B1 --- d=12m31s 19:42:20 Turban 0m23s 19:45:08 Vent 3m11s 19:54:04 FP 12m07s 19:54:27 P1 12m31s 19:54:39 V&T Quit 12m42s ΣD=12m31s
Shortly after that, several of us sitting on the benches felt a sharp thump, much like the ones you get at Oblong or Artemisia. Have no idea what caused it, as there wasn't anyone near us on the boardwalk. As we left, we saw West Triplet overflow, but it didn't have any convection or thumping.
From there, went directly out to Fountain Group, on the off chance that we might get another Morning eruption. After about two hours of waiting, we got an eruption of Morning's Thief. That was followed within a minute or so of the start of Fountain.

For a double interval, the wait for the One Burst Grand eruption wasn't too long or cold. The eruption itself was nicely backlit but otherwise undistinguished.

Decided to ride the bike over to Biscuit Basin for some photos. There were a fair number of people pulling up to the close entrance road while I was there. None of them actually got out of their vehicles or even turned off the engine.
Sawmill was in eruption when I went out to see Grand, and was still in eruption over five hours later. With a deep drain in progress, I started taking some videos of the area. Got Oval Spring having constant low pool surging, some Spasmodic northwest vent activity, and a Penta steamphase minor. By that time Sawmill finally stopped, so it was time to transfer attention to Uncertain, which started looking good during the Penta activity. Fortunately, it took its time. During the wait, I managed to record a couple of low pool, no overflow eruptions of Sawmill, and finally got Uncertain erupting.
By the time Uncertain had finished, it was time to move over to Grand. We were over 7-1/2 hours into the interval when Beehive's Indicator was noticed by the NPS. So once again, the benches at Grand emptied. The Grand eruption started right after the end of Beehive's eruption, but it was a nice but short two burst eruption, so most who had went to Beehive made it back. The eruption lasted less than ten minutes, and there was no attempt at a third burst.

When we arrived at the Fountain Paint Pots parking lot, there weren't any lights in the distance. We quickly got our gear together, and were about to leave when sudden there were lights and the sounds of people yelling. We hurried over and caught about two-thirds of the second Morning eruption of the year. It was nicely illuminated by several torches, and there was no wind, so Morning was not hidden behind Fountain and Clepsydra steam clouds. After Morning ended we stuck around for the Fountain eruption, which lasted about three quarters of an hour.
When we returned to the cabin, it was time for Grand. We had just arrived when Castle started to erupt. A few minutes later I heard some booping, and we got the One Burst Grand eruption. There was a slight breeze which helped move the steam away from our view. Unfortunately, it was another short eruption with no attempt at a second burst.

By this time Castle was in full steam phase, so we spent a little time watching it slowly die down.

Observations for 2024 September 07
The call for Beehive's Indicator went out around 23:00. With all the long durations, that meant plenty of time to get properly dressed and prepared for a calm, well lighted eruption. Little Squirt was also active at that time.
I missed it, but it turns out that at the same time, Rift was erupting. Not sure when it started, or for how long it erupted, but the next morning at dawn I found Grand an empty crater, and Turban had what appeared to be a normal eruption, so the previous interval wasn't excessively long.
Came back out about 2-1/2 hours later and Grand was well into overflow. Then proceeded to wait for nearly four hours for the mid-day One Burst Grand Eruption. As with many recent eruptions, this one started with a series of boops over a period of about ten seconds.
2024-Sep-07:13:15:38 T1Q 13:15:25 Vent Ovfl -0m13s 13:15:29 Boop -0m09s 13:15:37 Turban -0m01s 13:15:38 B1 --- d=10m49s 13:18:19 Vent 2m40s 13:26:28 P1 10m49s 13:27:16 V&T Quit 11m37s ΣD=10m49s * * * * * 09:48:59 d=04m13s 10:07:05 Int: 18m06s d=04m14s 10:26:14 Int: 19m09s d=03m58s 10:47:54 Int: 21m40s d=04m11s 11:08:00 Int: 20m06s d=04m22s 11:26:54 Int: 18m54s d=03m48s 11:45:19 Int: 18m25s d=04m17s 12:04:43 Int: 19m24s d=04m02s 12:22:37 Int: 17m54s d=03m56s 12:39:59 Int: 17m22s d=03m55s 12:58:22 Int: 18m23s d=03m41s Turban: 17m14s
After lunch, caught the mid-day Beehive eruption. For some reason, the boardwalk was nearly empty, despite (or because) an Old Faithful eruption being due. Old Faithful had a large preplay midway during the eruption of the Indicator, which ended up causing both geysers to start erupting within moments of each other.
The Sawmill eruption I saw start in the morning finally ended shortly after Grand, so after about 2-1/2 hours, I went out to wait for Uncertain. Sawmill was first rising, then started to drop. About this time Uncertain began to splash up, and we could see the water level in the vent. This level kept getting higher as Sawmill dropped. Finally Uncertain started to overflow. This lasted about 15 seconds, at which point the eruption finally began.
The next interval for the One Burst Grand eruption was surprisingly short. I expected it in the dark, but it was light enough to record video of the eruption, which once again started with a prolonged series of boops.
2024-Sep-07:19:37:29 G1Q 19:37:19 Boop -0m10s 19:37:29 B1 --- d=10m20s 19:38:02 Vent Ovfl 0m32s 19:38:06 Turban 0m36s 19:40:53 Vent 3m23s 19:47:49 P1 10m20s 19:48:50 V&T Quit 11m20s ΣD=10m20s * * * * * 19:18:02 d=04m24s Grand: 19m27s
As I was leaving Uncertain earlier in the day, I heard the radio call announcing that Morning Geyser had erupted. With Grand erupting sooner than expected, we decided that it made sense to at least head out there and see what might be happening. There was a small group of people who had heard of the eruption and were hanging around there. Waited for the crescent moon to set, about 45 minutes, during which time nothing happened. Water level was out of sight in Fountain.
As we were leaving, we saw a light approach from the Paint Pots. Suddenly the light veered off the boardwalk at the Volcanic Tablelands sign and headed north toward the trees. I had the powerful flashlight and lit the person up. He immediately and quickly headed back to the walkway, then continued toward us. For the next half hour, he wandered around the area as if wanted us to ignore him. In any case, he finally drove off.
It's true that we harassed him, but I would have ignored him completely if he had stayed on the walkway. As it was, I wonder if he had a campsite over behind that sign. Too bad for him Morning erupted.

Observations for 2024 September 06
Was quite surprised to learn that Grand erupted shortly before dawn. Had expected (and planned) on it erupting several hours earlier. The interval was so long that I suspected a Rift eruption, but when I got out there, it was obvious that Rift had not erupted overnight.
So instead I spent some time taking videos in the Sawmill Group. Got to see heavy bursting from Spasmodic as it dropped, Oval Spring having good size bursting from the north (front) vent, multiple eruptions of Tardy, the end of a Sawmill eruption, and a Penta steamphase minor.
Missed the start of the last item, as I was set up to record Bulger and Old Tardy (which ended up doing little to nothing), but quickly moved the camera over to Penta. Once that was over, it seemed like activity in Bulger did pickup a little.

After Sawmill restarted, I took a break, and got back in time to begin waiting for Uncertain. At first Uncertain was making lots of gurgling sounds, with an occasional visible splash. Then, quite quickly, Uncertain became quiet. That turned out to be due to it rising in the vent. We witnessed a couple of floods coming from the vent before one of them triggered the Uncertain eruption.
After that, it was a bit early, but still time to wait for Grand. I wasn't paying close attention when I realized that Grand's pool was full and having small waves at the six hour mark. Got the camera started in time to capture a couple of the strong boops. As expected, the pool level quickly dropped well before Turban finally erupted.
Three Turban eruption intervals later, we got a repeat of that performance. This time there were at least five boops, with several well over a meter high. Turban finally erupted just after the 25 minute mark.
So once again we had to wait three more Turban eruption intervals. This time the pool filled early, around the fifteen minute mark, but did start having wavelets until several minutes later. Again, there was some booping from Grand, but this time we finally got the One Burst Eruption, which lasted well over eleven minutes, with Vent & Turban quitting within a minute, and restarting within another six minutes.

The next Grand eruption would be in the dark. Unlike the last few intervals, however, the wait for this One Burst Grand was short, only 6-1/2 hours. The Turban eruption interval was not quite long enough to be a delay. Once again the eruption started with several boops. We heard the first one in the dark, 15 seconds before the eruption.

Did another half-hour video of Sawmill erupting, with Tardy frequently active. About a minute after I stopped recording, as I walked past Belgian Pool, Sawmill quit. Which was something I would've liked to have recorded.

The wait for the One Burst Grand Eruption was three hours of Turban intervals without any Turban Delay interval. Unlike so many one burst eruptions recently, this one lasted nearly eleven minutes.

Did not participate in the long wait for Beehive to erupt, but did get out for the 25 minute long indicator. Once again, it was a mostly windless eruption, although there was an attempt at the breeze moving the spray toward the boardwalk.
In the evening, Grand was set up again for a sunset eruption, but unfortunately there was a real Turban Delay interval of nearly 33 minutes. The One Burst Grand didn't occur until six more intervals had passed, but it was still light enough to see details in the pool. There was a sharp false pause just short of the eight minute mark, and the whole eruption lasted just nine minutes. There was no attempt at a second burst, but at least Vent & Turban continued.

It appears that overnight there was at least one long Grand eruption interval, since it was a double interval of sixteen hours. Otherwise the One Burst Grand was the common variety where it lasts less than 10-1/2 minutes. Vent & Turban seemed like they tried to quit, but then the activity picked up considerably, with Vent roaring as if something else could happen.

In the evening there was another long series of Turban eruptions without there being a Turban Delay interval. During that time we saw a couple of Daisy eruptions and a nice tall and wide Oblong eruption. Two Turban intervals before the Grand eruption, we had what appeared to be an attempt at an eruption. That eruption was also short and weak. The next Turban interval after that was one where Grand had little to no overflow.
The Grand eruption started at about the last possible moment. It was two bursts, with the second burst starting with Grand's pool in the shadows. A faint rainbow was visible near the top of the water column, which shows how low the sun was. That burst also lasted almost 2-1/2 minutes, with much of that time taken up with Big Sawmill mode.

For the morning Grand, once again had a short wait for the One Burst Grand eruption. West Triplet did overflow for a while after the eruption, but this time there wasn't any convection or thumping.

Going out for the next Grand eruption, as I passed Crested Pool I noticed that it seemed the ospreys were making a bit of noise. Then I saw the reason-- there was an eagle flying low headed upstream.
The wait at Grand was a long one. As we approached the eight hour mark, Grand finally looked like it might erupt, only to suddenly drop and then sit for long enough for it to be a Turban Delay interval. As expected, Grand finally had it's One Burst Eruption four Turban eruption intervals later. After the eruption, I noticed that the runoff from West Triplet was wet, indicating that West Triplet probably had a decent overflow during the Grand eruption.

Before the Turban Delay, Beehive's Indicator was called over the radio. Not only did this cause a mass evacuation of most of the gazers who had been waiting, but it appeared that many of the visitors followed them, as the benches seemed empty.
After Grand erupted the Sawmill Group was in the proper state for an Uncertain eruption. Uncertain was noisy, but there wasn't much splashing. After waiting about half an hour, suddenly Uncertain's vent filled with water, and with 15 or so seconds, the eruption started. As the Uncertain eruption was ending, Sawmill started to erupt. That eruption lasted for about 50 seconds, and then all was quiet.

Once again out at dawn in case Grand ignored the Rift eruption and had another shorter interval. There were three bison grazing on both sides of the bike trail just across from the store as I rode out. It was warm enough that there wasn't any ice on the walkways, and the sky had cleared enough that the sunrise wasn't brownish-orange. Didn't have to wait long for the Grand erupion. While the first burst was moderatly long, the second wasn't totally unexpected.

Spent the rest of the morning at Artemisia, which showed no signs of trying to erupt.
The afternoon Grand also had a short wait. Despite the One Burst Grand lasting over ten minutes, the pool refilled enough to be seen sloshing about for about fifteen seconds before finally draining.

It was not quite dark when I pulled up to the bike rack and Castle started to erupt. Unfortunately, it was a six minute minor.
So went over to Grand where I noticed that West Triplet had a wet runoff channel. Then waited one Turban interval for the Grand eruption. Turban started the eruption, but with the bright lights deployed, we could easily see the strong waves and boops. It had two bursts, and lasted just under ten minutes, with no attempt at a third burst. It's interesting how these short two burst eruptions cause Vent & Turban to quit.

Observations for 2024 September 01
Got out early because there were no reports of any activity overnight. Arrived at Grand near the six hour mark, and the pool was full, indicating it had been more than a few hours since the previous eruption.
Caught a Castile minor eruption, then two Turban eruption intervals later got the One Burst Grand eruption. When I arrived at Grand, the boardwalks were clear, but were slippery with ice by the time Grand erupted.

Then it was time to revisit Artemisia to look for a part from my camera tripod that was last seen after yesterday's eruption. (I found it.) Also took the opportunity to record some video of East Sentinal boiling heavily.
By the time I arrived back in the cabin, the start of Beehive's Indicator was announced over the radios. So went out for a nice eruption with calm winds and a double rainbow.
Early afternoon I arrived at Grand to what was probably a Turban Delay interval. I didn't see enough of that interval to be sure, but all the other indications (long Turban eruption, no overflow from Grand on the next Turban eruption) were there. The Grand eruption may then have been the fourth after a Turban Delay. Turned out to be the first observed two burst eruption since the three burst eruption. The duration was less than ten minutes, and Grand made no attempt to have a third burst.

With Rift erupting, decided there was no point in going out for the next Grand eruption early. I finally arrived at about the eight hour mark, just after the end of the Rift eruption. The Turban intervals and durations were both short. Ten minutes before midnight, Grand suddenly erupted. The eruption was over before midnight. It appeared that there was no attempt at refilling and having a third burst.

Observations for 2024 August 31
Figured the double Grand eruption interval would put the eruption well into the morning, so didn't head out early. A report of Grand not overflowing with a Turban eruption helped narrow down the time, too.
After 45 minutes, we got a long Turban Delay interval, which fixed the prediction quite a bit. The One Burst Grand eruption was four Turban eruption intervals later. The duration was a disappointing 9-1/3 minutes, with Grand making no attempt at a second burst.

Afterwards it was pointed out that an Artemisia eruption hadn't been seen since yesterday. It being a nice warm day with only a slight breeze, I decided that here was the opportunity to make a video of an eruption. Only had to wait about 1-1/2 hours, and suddenly heard and felt some thumps. The wind was away for most of the eruption, so had an excellent view.
Then on the way back, just as I approached the Lodge, came the call that Beehive's Indicator was starting. So went on over for that eruption. The wind was still a bit variable, and I had to get out the umbrella even though I thought I was in the safe zone at the eruption start.
Finally got a late evening eruption of Grand. No Turban Delay intervals, and the interval was only about 7-1/2 hours. The One Burst Grand eruption lasted just over ten minutes, and once again, there was no attempt at a second burst.

While leaving, noticed that Spasmodic was just starting overflow. Uncertain wasn't making much noise, but Sawmill was high. A few minutes later Sawmill started. Penta, meanwhile, was showing water splashing in the Top and Bottom Vents. This activity continued for about 1/2 hour, during which time Spasmodic dropped below overflow. Penta was still splashing around as I left.
Coming back from dinner in the Bear Pit, I was riding my bike when I encountered an animal just after I entered the cabin area. At first I thought it was a small coyote, but when I shined a light on it, it turned out to be a large fox. I ran past me and disappeared between some of the cabins nearer the Lodge. Now, if only it would harvest a few of the squirrels that insist upon coming in the cabin when the door is open.

Observations for 2024 August 30
Got up at dawn expecting to confirm that Grand had erupted recently, and that was the case. Based on the empty vents and lack of activity, I put the eruption around 05:00. I also noticed that Castle was having a deep, rumbling steam phase, also indicating that there had been a major eruption much earlier. Sawmill was also in eruption, but Spasmodic had a wet runoff channel, and looked it was near overflow again, but I didn't stay to see if that would happen.
The wait for the midday Grand eruption was relatively short. Saw Turban in eruption, and the next eruption was about 33 minutes later, so definitely a Turban Delay interval. Shortly after, a bison wandered across Grand's runoff channels, headed toward Economic. The One Burst Grand eruption came four Turban eruption intervals later.

Afterwards, noticed that Uncertain was having occasional splashes while Sawmill was low. The latter slowly rose over the next half hour, and the splashing in Uncertain decreased, until Sawmill finally did erupt.
Once again, arrived to a Turban Delay Interval. This time saw the preceeding eruption from the bike rack, and there was a small boop that resulted in and immediate drop in Grand's pool level. On the third Turban eruption there was strong overflow, and the subsequent Turban eruption had no overflow, but it lasted far too short to be a true Delay. Then on the fifth interval, Grand had another Turban Delay, just over the limit. The One Burst Grand eruption was just visible in the twilight. Toward the end of the eruption, there were several slowdowns that behaved like Grand was trying to pause.

Observations for 2024 August 29
Another day of Grand erupting in the morning at about the same time I my alarm went off so I could head out to see an eruption. Then again, correlation isn't always causation.
And Beehive erupted a few hours later. Once again, it was calm until shortly before the eruption when the wind started shifting about. Had to use the umbrella.
Before the next Grand eruption Uncertain looked promising, with Sawmill low, but slowly rising. Then Sawmill had two bursts, as if an eruption was starting, neither of which got much higher than the crater rim. That seemed to kill any chance of Uncertain, and the acual stort of Sawmill a few minutes later meant it was time to head over to Grand.
Also had to use the umbrella at Grand. After another series of non-descript Turban eruptions and intervals, Grand had a One Burst Eruption in what seemed like calm conditions. So much so that the people down by West Triplet and Rift got wet. Then the wind started swirling around, and the benches at the main runoff channel got soaked too. Then back to the south.

The next Grand wait started at sunset. For once the interval was not atrocious, and the conditions were much better than last night. The One Burst Grand eruption was well illuminated, and the rain fell in the usual location to the northwest.

Observations for 2024 August 28
It was a windy, cool morning. The temperature was only 50F, but the wind made up for it. The wind also blew the water column from Beehive right at most of the railing.
Once again, just missed a Grand eruption at dawn. I was a bit surprised that there would be two short intervals following yesterday's long wait. The wait for the mid-day Grand eruption wasn't so bad, just under 7-1/2 hours.
That eruption started out fairly normal, but with a lot happening in a short period of time. From Vent Overflow to Boops to Turban Start to Grand Start took twelve seconds. That first burst lasted only 7m18s, which either meant we got to see the shorted Grand in years, or were going to get a second burst. That second burst lasted exactly 75 seconds, just enough to qualify for a "*" marker. The last 30 seconds consisted of Grand trying to stop, but instead boiling up in Big Sawmill Mode. With the total duration at that point under nine minutes, again not surprised when we got a third burst. There was no attempt at a fourth, and Vent & Turban shut off within half a minute.
While waiting for Grand, I noticed a small sput to the south/right of Sput D. At first I thought it was activity from Sputnik, but after getting closer, determined that it was Sput G, which I first noticed about this time last year.

After Grand I noticed that West Triplet was full. About nine minutes after Vent & Turban quit it started to overflow. After about two minutes, with water pouring out, thumps started, and collapsing bubbles could be seen down in the vent. This lasted for about a minute and a half, with overflow stopping shortly after.
