Got up while still dark to check on Fan & Mortar. They hadn't erupted, and in the brief time I was there, all I saw was splashing from Angle Vent. So it was off to Grand.
It was light enough that the flashlight was no longer needed, and warm enough that the walkways were not frosted and slippery. It was another One Burst Grand eruption but it also closed a short double interval.
Watched East Sentinel for a bit, long enough to see a cycle of about 20 minutes between heavy overflows. Then spent three hours at Fan & Mortar. At first it was garbage mode, but everything got quiet for about eight minutes before Fans vents turned on. Later there was a hit of steam from the frying pans, and what seemed like heavy steam from Upper Mortar, but nothing much came from that. Then it was back to garbage mode, with Angle having minor blips every minute or two, and the other vents coming on strong for a minute, then quitting for a few minutes.
The midday Grand eruption had a Turban Delay with a small Grand boop followed by about five minutes of the pool slowly dropping. It was three more Turban eruptions before Grand started, and unlike many Delay starts this year, it was initiated by Grand.
The rest of the afternoon was devoted to killing time down basin. Toward sunset, it was time for Grand again. This time there was not only no Turban Delay, but the One Burst Eruption started with the sun still barely above the horizon.
