Observations for 2023 August 16


When I saw that it had been over seven hours since the Grand eruption we were at last night, I went on out again. Waited a full Turban eruption interval and then got a steamy One Burst Grand that lasted less than 9-1/2 minutes.

With Beehive active before dawn, it seemed like a good Lower Basin day. Since nothing expected from Fountain for a few hours, rode the bikes out to Great Fountain.

Arrived there and the water level was high, but well below overflow. After an hour, and several White Dome eruptions, Great Fountain overflowed for a few minutes, the receded below the level it was at when we arrived. It was another 40 minutes before the real overflow began.

The overflow lasted 80 minutes, and up until the 70 minute mark, we had the place to ourselves. During most of that time White Dome was quiet. That's when two families arrived. The pause at the start of the eruptions lasted about 1-1/2 minutes. The action wasn't Great Flounder class, but was definitely nothing big or spectacular. There were a few nice bursts angled toward the benches.

We stayed until the end of the third burst. On the way back Pink Cone was in eruption, which was a nice bonus.

When I went out to Grand for the sunset eruption, there was so much overcast (and probably smoke) that the sky was mostly gray. West Triplet was just starting to overflow, which is the first time I've seen that since early in this visit.

After a couple of Turban eruptions, Grand started to behave as if there was going to be a Turban Interval Delay. At around the 23 minute mark the boops started, and lasted for a full minute. Some of the boops were several meters high and wide. The start of Grand's One Burst Eruption was weak, but it lasted almost 12-1/2 minutes with few slowdowns. It took over a minute for Turban to start erupting, and it was finished within seconds of the end of Grand's activity.
