No rain for several hours, but it was heavily overcast and the fog seemed to be forming. Walked up to Grand, and had enough time to put down my pack as the eruption started. It was a foggy, One Burst Grand Eruption and so I was able to leave quickly.

Went over to Geyser Hill to wait for Beehive. Abandoned my wait when the rain started, but it finished by the time I got back to the cabin. It was only a few minutes later when the radio call for the Indicator came out. This eruption was actually nice because few people around and the little breeze we had was away from the walkway.
The rain was only supposed to last an hour or so, but four hours later it was still raining as I went out for the next Grand eruption. I decided to walk via Geyser Hill as I've found riding a bike in the rain is a sure way to get soaked no matter how hard I try to stay dry.
As I came out into the clearing by Liberty Pool, I saw Penta in eruption. It was a steamphase eruption, and I must have seen it near the start as the activity didn't diminish in the time it took me to walk over to it. Sawmill was off, and the pools of Spasmodic were not visible down in the vents. There was horizontal jetting on the south side of Spasmodic also. Oval was also low, and the near vent was surging a half-meter or so.
I think I arrived at Grand for the first Turban eruption after a Turban Delay Interval. The pool started out looking low, and there was little to no overflow before the next Turban eruption. If that was the case, then the One Burst Grand Eruption took place on number five (D5). The rains continued during the wait, despite all the weather reports and radar maps showing we were supposed to be clear. So the eruption was steamy and unimpressive.

During the wait there was also a Castle minor eruption. Didn't get the duration because I was not moving from my dry spot from which Castle wasn't visible.
It had been almost two hours since I saw the Penta activity, and Sawmill was still quiet. Was hoping that meant there might be a possibility of Uncertain erupting. Instead, Sawmill started right after we'd walked up to it. The splashing in Uncertain did get stronger, but never close to looking like an eruption was starting. At the same time, Tardy had a series of short bursts, then started gurgling at depth.
Once again, I walked up on an eruption of Tilt while headed out to Grand. And at Grand I believe I caught another Turban Delay Interval eruption, because this Turban eruption lasted over six minutes, and the following Turban interval was short and without overflow.
Four Turban intervals later Grand erupted. The sun was below the horizon and clouds, but there was hints of pink and magenta in the clouds behind the Grand eruption, and more than enough light to see by. The day was never warm, so much of the eruption was obscured by steam. Grand quit at just over nine minutes, and the steam parted enough to see the pool, which was still full. So a several day string of one burst eruptions was finally broken.
