Observations for 2025 May 29


There was a report of a rumor that an aurora was visible, do headed out to Grand a little earlier than originally planned. All I could see was glow along the northern horizon, so it wasn't much and didn't last long.

Then waited an hour for the One Burst Grand eruption, which again lasted under 11-1/2 minutes. The Grand eruption seemed foggier than usual for an eruption at that time of day. Nowhere along the boardwalk was there a place where fog didn't obscure and scatter the beam of light coming from the light.

Got out early in the morning in case there was another short interval. Instead, after about an hour, got a Turban Delay interval. The One Burst Grand eruption finally came seven Turban eruption intervals later. This time the eruption lasted less than ten minutes, a slight change from the recent One Burst Grand eruptions.

During that wait I checked on Economic. It was still just below overflow. The area around was wet, and it might have had a slight trickle on the southwest side.

The Bijou Monkey Cage by Giant has been rebuilt exactly as it was before, with the benches and large sign in the same locations.

For no apparent reason, in the afternoon Grand had an eight hour interval prior to another One Burst Eruption. Midway through the wait the weather to the northwest started to look bad, and the radar maps showed an approaching storm. But the storm never really materialized, it was just windy with occasional sprinkles.
