It seemed to be calm for the pre-dawn eruption of Beehive, but there was just enough air movement to cause the spray to thoroughly wet down the walkway along the railing.
Decided the night before that there was no reason to get out to Grand before it got light. Didn't set an alarm, expecting to get out when I did wake up. Arrived out there at the 8-1/2 hour mark and found a full pool. Two Turban eruption intervals later, there was heavy overflow signaling that the eruption was about to start. The One Burst eruption at least lasted well over eleven minutes. By the end the tops of the highest jet were illuminated by the sunlight coming over the trees.

Percolator was quiet the short time we were waiting out there, and during the Grand eruption West Triplet went from empty to starting to erupt shortly after Grand ended.
Went out again for Grand's first overflow. This time it took place at 4h35m, which is a bit more like what I'm used to seeing. But it also took place during a Turban Delay interval of nearly 32 minutes. Just after the previous Turban eruption the pool was extremely low, and by the 15 minute mark it appeared that first overflow was not going to happen that Turban interval. But because of the Delay, the pool kept on filling instead of the expected drop, and the overflow started a the 24 minute mark.
At that point the clouds to the west looked like rain, and I headed back in, just in case.
Went back out to Grand around the seven hour mark, with the weather radar map showing most of the showers were streaming past to the south and east. The Turban durations were short, between 3m15s and 2m30s. After an hour, West Triplet began to erupt. Twenty-four minutes in, Rift also began to erupt. West Triplet continued to erupt, finally ending with a duration of 54 minutes.
At about an 1-1/2 hours into the Rift eruption, Grand had a Turban Delay interval. Shortly after Turban ended, so did Rift.
The Delay ended up being only two Turban eruption intervals, and we got a One Burst Eruption which started after about 8-10 seconds of booping.

Went out later around sunset to Geyser Hill intending to record some videos, but Slot erupted just as I got to Giantess. That video will have to wait.
