Got out to Grand just before midnight, and in the few minutes before Turban erupted there was no sound of overflow coming from Grand. It was the same for the next Turban eruption. It appears that we arrived just in time for the first Turban eruption after a Turban Delay interval. If that was the case, then we finally got the One Burst Grand Eruption after seven Turban intervals. WHile not as steamy as the previous night, it was not possible to see the starts of Vent and Turban.

In the morning, went out to Grand at sunrise, just in case there was a short interval. Only had to wait an hour for a long Delay Turban interval, but fortunately Grand's pool refilled. That took almost 1-1/2 minutes. The One Burst Eruption lasted 8-1/2 minutes, and Grand made no attempt to have a second burst.

Down at Economic the pool was almost exactly at the point of overflow. The area around was wet, so this may have been higher until just recently.
With nothing much going on, decided that since it had been well over 24 hours, it ws a good time to check in with Artemisia. On the way, as always, stopped by to check on East Sentinel. It was as I've never seen it before-- completely quiet. No evidence of any boiling along the edges. The pool was in good overflow when we walked up, but then suddenly dropped about 4cm below overflow. Then it slows rose back and started overflow a bit once again.
Artemisia was full, and we waited only about 2-1/2 hours for an eruption. The wind mostly cooperated for video taking. Early in the eruption Atomizer had a minor eruption.
On the way back from Artemisia, East Sentinel appeared unchanged.
The wait for the third Grand eruption of the day was uneventful. Once again after a few Turban eruption intervals we got a Turban Delay Interval, which resulted in Grand erupting. For well over a minute Grand was pulsating and pouring off water before we finally got the first boop. At the end Grand had water in the crater for maybe 20 seconds before finally dropping.

In the early evening I to wait about 20 minutes to get onto Geyser Hill due to a couple bison who crossed over the boardwalks at the junction heading in opposite directions. Once there, didn't have a long wait for Beehive to erupt.
The Indicator was not erupting when there began a long sustained surge. After several seconds, it built into a sudden start. The eruption was long, lasting nearly six minutes, and there was a nice rainbow from the northern end of the benches.
Went out to Grand with the expectation of having a four Grand eruption day, as the six hour mark was at 22:00. Grand ended up having a five Turban Delay interval, erupting on the last possible opportunity. Then the One Burst Grand eruption, lasting only 9-1/2 minutes, had Vent & Turban quitting. All nicely disappointing.
