Since there was no reason to make the trek to Norris, slept in. Out to Grand for a steamy One Burst Eruption.
Then stayed around for a couple of hours to see what would happen next. Just before Grand's eruption Sput D erupted, and West Triplet overflowed. This happened about every twenty minutes until Vent and Turban finally quit. The overflows lasted about four minutes, and the activity from Sput D was at or just before it started, and then about the time it ended. On one of the overflows, Sput A was seen bubbling, along with frying pan activity in Sputnik (Sput B) and a new (or at least a hole I don't remember) bubbling about two meters from Sput D and to the right of A.
When Vent and Turban finally quit, West Triplet came up one last time, but not close to overflow, then dropped down into its tube. I left about 40 minutes after the last overflow.
Returned about an hour and a half later to catch the first overflow. Has been years since I did that, and in previous times it was always about 4h20m except back when Rift had an effect on Grand. Then it could be six to seven hours. Arrived to find West Triplet's runoff dry, which would be a good indication there hadn't been any more overflows since I left.
The activity from the sput seemed to be synchronized with Turban at first, but after about an hour it was out of phase, then it quit entirely. It was next seen right before the time Turban would have erupted if it hadn't been having a Delay. When Turban finally did erupt, it was followed by more activity from Sput D, as well as another eruption after the next Turban. I wasn't in a position at that point to see what West Triplet was doing, but it didn't look like there was any runoff at any of these times.
So we got a One Burst Grand, and afterwards as I was leaving, saw West Triplet have a short, heavy overflow without any activity from the Sputs.
