Observations for 2025 June 11


The moon was bright and the sky clear when we went out for the after midnight Grand eruption. That situation slowly deteriorated, with high, thin clouds moving in and staying.

Got out just in time for a long wait for the first Turban eruption. That was preceded by heavy overflow and it was a strong Turban eruption. The next Turban eruption had no overflow, so the Delay count began.

A couple more Turban intervals and we got an eruption of West Triplet. That's when the Turban eruption intervals and durations began to vary in length, with little pattern. At one point there was heavy overflow and an interval under 24 minutes, Another time there was a short Turban eruption and an interval below 15 minutes.

By that time it was getting light and the moon had set. After a second West Triplet eruption, the fifteenth Turban eruption had an interval under 15 minutes, and a length under three minutes. Then we got a second Delay interval of over 32 minutes. It was two more short Turban intervals before Grand finally erupted. With a duration of just over nine minutes, that could've been the only burst, but at least our long wait got a second burst.

We started to feel raindrops on the way back from that eruption.

After an attempt at catching up on sleep, went out again for Grand. West Triplet was in eruption, and about twenty minutes after that Rift joined in. No Turban Delay intervals this time, but did have to set through about twenty minutes of rain and strong wind as a line of showers passed through. Then the rain stopped, although it was still cloudy with no sun.

An hour and a half into the Rift eruption Grand had a nice steady fill on a normal Turban eruption interval. Grand still took well over a minute to begin erupting, and this time the One Burst Eruption lasted 9-1/2 minutes. On the way back got to see a distant Beehive eruption from next to Sawmill. And once again, there was a hint of rain on the way back.
