Looks like the Grand Group has settled into a routine. No real change from the last few days, where we have Sput D erupting before and after Grand, but taking a bit of a pause in the middle of the interval. Grand itself has some shorter intervals, but then tosses in a longer one so that it is erupting at the same time of day every day.
But we did get some interesting One Burst Grand eruptions. The first one, in the morning, had Grand lasting 9m33s, followed by 1m45s until it drained. Unusual to wait that long, and Vent & Turban quit almost immediately.
But the afternoon eruption was probably a record setter. I cannot remember a One Burst Grand eruption that lasted longer than about 13m30s, and this one had a duration of 14m21s. For the last few minutes it really did go into Big Sawmill mode, where most of the activity consisted of low surging and boiling punctuated by the occasion sharp, high rocket. When it finally quit, it wasn't all that sudden, it just sort of died down. Turban finished moments before Grand did.
