Observations for 25 May

When I came in from the night, I was thinking that if it stayed clear, it looked like we were in for some significant fog. It was already starting to form in some areas. Instead, tday started out looking like it was going to be a continuation of yesterday, with a solid gray sky that had to rain. But by about 08:00 it had already broken up, so what we had may have been just the fog I expected, but a bit higher. From Lower Ham's, I could easily seen the fog banks of Midway and Lower Basin to the north, but there also people said it wasn't that bad.

One thing people don't realize is that a Rift delay doesn't always happen after Rift starts. Sometimes the delay is that wait you have from one West Triplet eruption without a Rift to the next one where Rift starts. This morning, though, we just had a long wait between West Triplet eruptions for no good reason. And while last night's two burst eruption was far too short, this morning we had nearly three minutes that could and should have been broken up.

Overnight, around 04:30 there were a series of small (1.9 to 2.9) earthquakes centered in the Lower Basin, somewhere between Thud Group and Porcupine Hills. It was felt by a few in this area, as well as campers at Madison. But it appears they had no effect that was visible.

On the other hand, the monitor confirmed that I did see a second minor at Castle last night, and we didn't get the major until 12:48. Despite the winds (from the north) Daisy's intervals dropped below 2 hours. And Beehive reminded people that just because the last few indicators were over 15 minutes doesn't mean it still can't toss in a 6 minute one.

The rest of the day was filler time. Daisy was having intervals below two hours, and Grotto started another marathon. Oblong wasn't reported, either. While waiting for evening Grand, Penta looked good like it did the other day, but once again, just as Penta was about to start, Sawmill took over.

The pair of coyotes who tried to harvest marmots behind Grand the other day were back during the evening Grand wait. They made two attempts, the first of which seems to actually have some planning, or at least appeared that way. The first one crossed the boardwalk between Rift and Belgian, and slowly made its way along the base of the hillside, right next to Grand. All the while the marmots were chirping, but the coyote seemed to not mind or care. A few minutes later the second appeared. This one quickly ran up the hill a ways before trying to snatch a meal. No such luck. About an hour later one of them appeared on the northern edge, again without success. In any case, it appears these two know that there are meals to be had behind Grand. Now if they can only acquire them.

Grand itself first waited for Rift, then for sunset before erupting. As it seems happens way to much to be mere chance, the eruption occurred on the last possible Turban before darkness. As it was, we even had a little light to see the way back. The eruption itself was another eleven minute long one burst, notable only for Turban and Vent continuing instead of their usual pause.
