Since Grand erupted during Rift's eruption last night, the expected long interval for Grand took place overnight. The first three observed Turban eruption durations were short, around three minutes long. Then we got a long Turban interval, but it wasn't long enough to qualify as a Turban Delay Interval. That Turban duration was a minute longer, as was the next eruption.
Grand finally erupted less than 16 minutes later. When the first burst ended at less than 8-1/2 minutes long, we were pretty sure of a second burst. Backlit by the sun with much of the steam cleared away, it seemed impressively high. And it lasted just over 1/2 a minute, which is short. Despite that, the pool quickly drained and there was no effort at a third burst, and a total duration of about 9m36.

Afterwards, in the Sawmill Group Uncertain was splashing. All the conditions looked good for an eruption. Waited a bit, and then suddenly Sawmill started. Despite that, Uncertain continued to splash, and a few minutes later it built into an eruption. This eruption seemed shorter than those I've seen in the past, but that may be due to erupting with Sawmill.
Later went out for the noon radio call for Beehive's Indicator.
In the early afternoon, went out to Grand a bit early, as not sure if the longer intervals due to Rift would still be in effect. Not a super long interval, but still longer than the day prior to Rift erupting. Had to sit through several small showers that were just enough to wet things down.
The first burst from Grand was long enough for a One Burst Eruption, but we were rewarded with a second burst. The pause was less than a half minute, and it looked like Grand's pool was down quite a bit when the bursting restarted. Usually I expect to see sloshing around for a while as the pool rises to near overflow. The second burst then lasted almost long enough to qualify as a Long Second burst, while the Vent & Turban restart took well over twenty minutes.

Since it was clear, and tomorrow is supposed to be cool and wet, we went out after sunset for another Grand eruption. The wait was uneventful. The One Burst Grand eruption had a false pause after a minute or so of Big Sawmill mode, then continued on for almost three more minutes.
