Visited East Sentinal early in the morning for about 40 minutes. The North Rim vent cycled every 15 to 20 minutes, briefly having a heavy overflow and some surging, then dropping back down for the next cycle.
Over at Grand, the walkways were icy, especially in the shaded areas (or where shaded by people sitting on the benches). I think Rift may have erupted a few hours earlier, as both Crystal and Belgian were high, and Slurp was in a wet eruption.
While waiting, I saw Bulger start, the first activity in days. A bunch of us quickly went over there and got to see Bulger's Hole fill and erupt. It still does its spitting and pausing. It also made noises as it drained.
Grand itself was another One Burst Eruption, starting at the end of a Tuban Interval Delay. A ten minute duration resulted in Vent & Turban quitting.
Then spent a couple of hours back at East Sentinel, where it still didn't do anything, just more cycling as seen earlier.
Grand then had a long interval for no good reason. It finally erupted on a 32 minute Tuban Interval Delay, where the pool seemed to be dropping at Turban started. It then came up and started flooding the area. A nine minute duration was enough for the pool to briefly refill before dropping for good. At least Vent and Turban continued.
