Went out in the dark to Grand near the nine hour mark. Walked up onto the end of an eruption of Rift. Water was still steaming away along the whole runoff channel. A little over an hour later there was a Turban Delay eruption interval.
During that Delay, Castle erupted with a minor eruption lasting less than three minutes. Finally five Turban eruption intervals later, right after eruptions of Daisy and Oblong. The One Burst Eruption lasted just over eleven minutes. Vent & Turban quit and restarted less than six minutes later.

Went over to Geyser Hill to get a video of Slot Geyser erupting. After that success, waited a bit for the call for Beehive's Indicator to start erupting. Considered waiting near Plume for the possiblities for rainbows, but despite the dead calm, decided not to risk that location. A good move, as about halfway through the Beehive eruption that area got rained upon.
Did another wait for Grand's first overflow. Once again, that occurred nearly five hours after the previous eruption, and again during a Turban Delay eruption interval. This time the overflow came early in the interval, and by the twenty-five minute mark Grand's pool looked full, as it does before an eruption. Then it quickly dropped before Turban finally erupted for a 32 minute interval.

Since this was the non-Rift interval for Grand, went out a little early. There were a few unintersting Turban eruptions where the intervals got progessively shorter. Finally an interval under 17 minutes that had an explosive start by Turban. Grand took its time getting the One Burst Eruption started. As I've noticed with several other eruptions this trip, the pause before Vent & Turban restart was around six minutes. In the last few years, that has tended to be longer, well over 20 minutes long.
