The middle of the night One Burst Grand eruption continued the number of short intervals I've seen recently. The sky was overcast, so not much opportunity for any meteor observing.
I did have to wait a Turban interval, but that one ended with another of those Turban starts where it just feels like Grand wants to start. The power of Turban, combined with the hint of steam getting thicker over Grand proved to be correct. That eruption was one of those with several minutes of Big Sawmill, padding the duration out to 12-1/2 minutes.
West Triplet started before the eruption, and right after Grand finally quit. Rift started.
Went out again in the morning for the next One Burst Grand. It was overcast, breezy, and cool. Got a Turban Delay with the first Turban eruption after arriving. This one even featured a small Grand boop several minutes before Turban started. Right after the boop, the pool dropped and kept dropping.
Ended up having a six Turban delay, although if one of the intervals had been about 30 seconds longer, it would have been a D2/D4. Several of the Turban intervals featured weak or no overflow from Grand, and short durations for Turban. It finally erupted on a short Turban interval where the pool was full by eleven minutes and then kept slowly filling with lots of waves.
The pool drained after the first burst, then refilled. It sloshed for over a minute before until Vent started having some powerful jetting, signaling the end. With the draining, Vent & Turban quit almost immediately.
Also got to see a Churn eruption from the benches right before the first Turban Delay. At some point, would be nice to see one up close.
The afternoon One Burst Grand was almost a repeat of the morning's activity. There wasn't a threat of rain, but it was overcast, cool, and windy. The interval was slightly longer even though the Turban Delay was for five intervals instead of six. West Triplet was ending an eruption as I arrived, and it started again during the Grand eruption.
All three Grand eruptions today were outside the NPS prediction windows. The first was before, the later two were after.
