Observations for 2023 August 05


It was cool and damp and foggy at dawn, but the rain finally seems to have stopped. Went out to Grand with the hope that the short interval were continuing,but instead arrived just in time for the first overflow. A couple of Turban intervals later, we got an interval lasting 36 minutes. So it was six more Turban eruption intervals before Grand finally erupted. The One Burst Grand eruption lasted over ten minutes. It looked like Vent & Turban were going to continue when instead after a minute they picked up and Vent started jetting noisily. Then they shut off. The pause before restart was about five minutes.

With no reports on Beehive, when over to Geyser Hill mostly to enjoy the dry and increasing sunlight. Ended up waiting over by Lion, which was splashing in anticipation of the first eruption in a series, but never did see an eruption. North Goggles was overflowing every nine to ten minutes during that time.

Finally did see Beehive, where the wind was such that the people over by the sign got doused and the railing remained dry.

Thought we were headed out to the next Grand eruption too early, but the benches were crowded. Turns out Castle had erupted earlier than the prediction, so all the people who would've stopped there for the shorter eruption prediction window headed on to Grand.

Turned out we weren't early. Once again Grand had a short interval. For about five minutes the pool fluctuated from just below full to having small waves. Finally one of the fills kept on going and had a One Burst Eruption.

After the eruption is when we finally got a thunderstorm with some initial hail. And once again, the rain stopped by the time the cabin was reached. Lesson is to just put on the raingear and wait it out.

Went out after sunset for another Grand eruption, ended up waiting until just before midnight for a One Burst Grand eruption. (G1C, d=9m57s). It was foggy and damp, but until the fog got too thick, the sky was clear and stars visible. There was also lightning off in the distance to the west. The moon was causing clouds behind Grand to glow, but was just rising as the eruption started. Afterwards the fog was so thick that it looked like all the lights in the developed area were off.
