The clouds of the day had cleared out by 22:30, so despite the experience of the morning, no reason to not to head out.
Might have arrived for a Turban Delay interval, because the overflow was strong and the next Turban eruption had no overflow prior.
If that was the case, then we only had a 3 Turban Delay before the One Burst Grand eruption. While the moonlight was clear and bright, I didn't see any moonbows while standing over by West Triplet.

It wasn't until we had left Grand that we realized that Castle was in eruption. Based on the fact that it was transitioning to steam as we walked up to it, the eruption started during Grand's eruption. This time we were able to catch moonbows with a slight hint of color in the spray and mist from the steam.
In the morning, I arrived just in time to catch another Turban Delay interval. West Triplet then erupted in the middle of a series of seven Turban eruptions leading to another One Burst Grand eruption.

During the wait we saw an eruption of Oblong, and unlike most of the others that have been witnessed from there, it had a number of tall burst visible through the steam of the eruption.
With nothing much going in the Upper Basin, decided to try for a mid-afternoon Great Fountain eruption. Arrived at noon to find a low Great Fountain crater.
So took a side trip to check out the road damage at the bridges. It doesn't look good, and I'll be surprised if the road reopens any time soon, because the repairs are more like replace.
The Great Fountain overflow started about 1-1/2 hour later, lasting about 85 minutes. It was windy, so the best observations were from the boardwalk benches. There were some bursts with good height at the beginning, but the first burst sort of gradually turned into the second.
Got back into the Upper Basin where Grand had not erupted and the interval was over seven hours. From the bike rack I saw an eruption of Turban that was so large that at first I thought I was seeing Grand in the late Big Sawmill phase. But no jetting, so I knew that couldn't be it.
A half hour later West Triplet erupted, followed a few minutes later by the One Burst Grand eruption, lasting 9-1/2 minutes. West Triplet ended after that, with no Rift eruption.

By then it was nearly 17 hours since we saw the Castle eruption, so decided to hang around. Over then next 1-1/2 hours the waiting crowd slowly got smaller as Castle was mostly silent with the occasional large splash. Needed time to fix a meal, so finally left around 19:00. Castle had the minor eruption about ten minutes later.
