Since the thunderstorms last night kept me from going out and seeing Grand, I went out at dawn not knowing what to expect. (Dawn is now after 06:00 and getting later every day.)
It was cloudy with fog down below. I got out to find Grand in heavy overflow that ended almost immediately, followed by Turban erupting. The next Turban interval had no overflow, and the next was a long Delay Interval.
After that, it was an uneventful wait until Grand filled nicely for the fourth Turban eruption. The One Burst Grand was a steamy mess, with a wind blowing steam and spray all over the northern benches.

Next it was down to the Bijou Monkey Cage. Over the a period of over two hours we saw a few Mastiff surges, but Bijou never paused. then there was a surge that, unlike the previous surges, started slowly instead of suddenly. That built into a the largest surge of the morning, and about then Bijou slowed and paused.
The pause lasted 3m09s. The water in Mastiff was at about the same level as yesterday. There were a couple of spits from the Southwest Vents, but no large surging in Giant.
I got the Beehive Indicator call in the cabin, and made it to the railing for the start of Beehive's eruption. It was windy, and no way I was going to proceed further.
An hour later it was time to return to Grand. West Triplet was in eruption as I tied down my bike. We only had to wait one Turban eruption interval, and the Grand start was a bit of a surprise. It also took Vent about 4-1/2 minutes to start. West Triplet ended early in the Grand eruption.

With the short wait, it was on to the Bijou Cage. After about a two hour wait with a few small Mastiff surges, we finally got a Bijou pause. This was similar to the activity we'd seen this morning, except this time the Southwest Vents were active during the last minute, putting out enough water to form pools on both the platform and the shelf below.
Finally went out for a nighttime Grand. It was mostly clear, and the gibbous moon was bright enough. Had to wait just over an hour, with no Turban Delay intervals, and finally got to see a two burst eruption. In the middle of the first burst, the moon disappeared behind a cloud, so the second burst was just barely visible. The total eruption lasted less than ten minutes, and then Vent & Turban quit.
