Observations for 2023 August 30


Made the mistake of assuming that since Grand had a short interval while Rift was erupting, the next interval wouldn't be too bad. Add in the fact that the moon was nearly full.

A minor storm came through just after dark, and while there wasn't much rain, it brought a steady wind. For the first hour or so, the moon was mostly hidden by the clouds, but then the sky cleared. Because of the wind, and despite the bright moonlight, very little steam was visible from Grand and Turban, which made it difficult to guage the status of Grand's pool.

Three hours and ten short, weak Turban eruptions after arriving we finally got a Turban Delay overflow. Since Grand didn't erupt, that meant it would probably be at least two Turban eruption intervals and 45 minutes before the Grand eruption, so we went back in. As it turned out, it appears there were probably four Turban eruptions, as Grand didn't erupt until 1-1/2 hours later.

Getting a Beehive eruption at sunrise was a minor consolation. The long Indicator eruption gave people plenty of time to get into position. It was still windy, and the wind shifted enough to make the few people there move back.
