I considered going for a moonlight Grand eruption, but at around midnight the moon was behind a cloudbank, and the weather radar map showed incoming showers in an hour or two, so I decided to stay indoors.
In the morning the rains had let up by the time to head out for the next Grand eruption, and again the radar map showed incoming showers. A steady rain started as I arrived. Fortunately I was able to set myself up and stayed dry the whole time.
West Triplet was also in eruption as I arrived, and the One Burst Grand Eruption started on the Turban eruption after the end of West Triplet. The eruption was just long enough to preclude a second burst.

The rains had stopped by the afternoon, but it was still cold, damp, and windy. Turban was in eruption as I arrived, and it didn't erupt again until over half an hour later. Fortunately, the wait was a reasonable four Turban eruption intervals. Grand even managed to start well before that interval would have become a Delay Interval. The pool was high with nice waves when everything happened in a matter of seconds. The duration of the burst was well over nine minutes, which is that intermediate range where the eruption could easily be one or two bursts. Fortunately, as the pause approached a minute, water could be seen through all the steam doming over the vent. Once again, it seemed like Turban quit at the same time as Grand. Also, West Triplet started near the end of the first burst.
