Observations for 2023 August 15


Grand wasn't erupting as I biked past the Lodge. It was erupting as I approached the Inn. I turned around and let others enjoy the One Burst Eruption (and it was one) to go back to sleep for a while longer.

A few hours later, was expecting Beehive, but probably not soon. So intended to wait over by Aurum for the Indicator call. Waited less than ten minutes. Between the call and Beehive's eruption, also witnessed the second Lion eruption of the series, and a Plate eruption. I haven't seen Plate up from on Geyser Hill in a few years, and it seemed to me that the eruption was much larger than way back then. Beehive itself erupted in almost dead calm condition, with the spray and condensation settling on the walkway down by Plume.

For the next Grand we only had to wait for a few Turban eruption intervals before we got the Grand eruption a bit late in its early window. The first burst lasted almost 9-1/2 minutes, so it was a pleasant surprise to once again see a minute's worth of sloshing about in Grand's crater before we got the second burst. Despite the length of the eruption, over 11 minutes, Vent & Turban did not quit this time.

For the next Grand wait, went out about three hours after the start of a Rift eruption. Did not expect or intend to be still out there four hours later.

When I arrived, I noticed a new sputtering hole, or at least one I didn't remember seeing previously. It is located about 1.5 meters from Sput D, directly on the line between Sput D and West Triplet. The vent is tiny, and the sputtering was only a few centimeters high. But it continued, along with Sput D's activity, as long as Rift was erupting. Until I can confirm that I didn't use the designation before, I'll refer to this as Sput G.

Sput G (in box) and Sput D erupting.

The second Turban eruption since my arrival was a Turban Delay Interval. From there, it took twelve more intervals before we finally got the One Burst Grand eruption. Rift itself ended after the fourth interval, for an approximate duration of five hours.

Just before Grand erupted we got a little diversion. Ben Vanderley noticed that Bulger was erupting, and it was a major. In the dark, the gazers waiting for Grand ran down there, to the confusion of various visitors who were still waiting in the dark for Grand. Within a minute of Bulger starting, Bulger's Hole began erupting.

It was a strong eruption, with heights to about 4 meters at times. The activity slowed down twice as if the eruption was ending, then came back strong. There wasn't any sound effects from the Hole when it drained. The total duration of the eruption was about three minutes.

After Grand we hung around Bulger in case there was a second major and Bulger's Hole eruption, but after about 1/2 hour it was obvious that the one eruption was it. As we walked away, we noticed that Sawmill was quiet and Uncertain was steaming gently. It seemed obvious that in the dark we'd missed an eruption, about 20 minutes earlier, perhaps during an eruption of Old Tardy.
