Observations for 2025 September 05


The string of One Burst Grand eruptions continued today.

First it was the one before dawn, which consisted of a series of short Turban eruption intervals before a short One Burst Grand eruption.

Then there was the One Burst Grand eruption that had a shorter series, but also had short Turban eruption intervals. This time Turban initiated the eruption, and it lasted over 11-1/2 minutes. West Triplet also started erupting just over a minute after Grand started. And once again, there was some large afterplay from Grand starting about five minutes after the restart. Disappointed that we didn't get the Rift eruption over with.

Just after dinner came the call for Beehive. During the walk over, also heard that Depression was starting to erupt, so I managed to capture that to video.

At the seven hour mark, Rift was in eruption, and had been so for quite a while. Only 45 minutes into the wait, Castle started to erupt, and it quickly became obvious that it was going to be a major eruption. A number of those waiting were going to go over there to look for moonbows, with Rift still in eruption. But on the next Turban eruption opportunity, it also became obvious that Grand was going to start, based on the strong Turban eruption.

There was a nice, short first burst, a fairly lot pause, and a short second burst. It was dead calm, and the jets of water rose above the building steam cloud. But once again, we got a two burst eruption lasting less than ten minutes, with Vent & Turban then quitting.

Castle was still in eruption, and had pretty much made the transition to steam, but was still impressive seen from the boardwalk, and there was enough spray to see a nice moonbow.
