Observations for 2022 August 30


Went out to Fan & Mortar at dawn to check on it. When I saw in the predawn light Angle splashing away and the rest of Fan quiet, I figured that there wasn't much reason to stick around. Went over to Grand instead, where the interval was already over six hours.

Probably arrived at the end of a Turban Delay interval, as there was no overflow from Grand for the next Turban eruption. The waited five more Turban eruption intervals where nothing much happened. When Grand did finally erupt, it was another short One Burst Eruption lasting well under ten minutes.

Reconfigured back in the cabin, then went out to Fan & Mortar again. No change from yesterday-- lots of Fan turning on and off, but nothing from Mortar. After three hours, I left.

Back out for Grand, where the water levels in Belgian and Crystal were as high as I've seen this year. Once again Slurp was drowned, but quiet. Again, I may have arrived as a Turban Delay started, as the Turban eruption lasted over 5-1/2 minutes and the following Turban eruption had no Grand overflow.

After six more Turban eruptions, Grand started over a minute after Turban, along with about ten seconds of boops before the eruption began. It was another One Burst Eruption that lasted under ten minutes.

Almost immediately afterwards, West Triplet started to erupt. These were full bursts, not the upwellings that break the surface that has characterized it the last few weeks. Fifteen minutes in, Percolator and Sput D were also active, so it was no surprise that after 26 minutes, Rift also started. This is the first Rift start I've seen this trip, and nice to know that it started with a normal West Triplet. When I left shortly after West Triplet ended (with a duration of 45 minutes), Belgian and Crystal had dropped several centimeters, and Belgian was barely covering the lobe.

Three hours later, there was a report that Rift was still erupting.

Made one last trip down basin, and after about 45 minutes, it was obvious that there had been no change in Fan & Mortar while I was gone.
