Observations for 2025 September 04


Another morning wait for Grand with the previous eruption time in doubt. But only a 1-1/2 hour wait before the One Burst Grand eruption, and did get to see from Sawmill the Beehive eruption. The start of Grand's eruption was one of those where the pool is nice and high early, and never drops or does something annoying.

West Triplet started at about the time it became apparant that this was going to be a long eruption. I waited for the end of that eruption intending to record the start of Rift's eruption, but for once I was disappointed that Rift did not erupt.

Afterwards realized that it had been an hour since the last report of an eruption of Tilt, so waited about ten minutes to record the next eruption. At least I didn't wait an hour there like the last attempt.

Went out to Grand prepared for a stay into the dark, and needed what I took out. First, West Triplet was in eruption as I arrived, and when it ended without a Grand or Rift eruption, I figured we had a few hour wait until the next West Triplet eruption.

During the wait, Grand had several early fills but then dropped. West Triplet finally erupted over three hours later, and the very next Turban eruption was a Delay eruption interval. Then 45 minutes later Rift started. Fortunately, Grand was able to have the One Burst Eruption two Turban eruption intervals later. The moon was brown, so the view wasn't great.

It was pointed out that the missing GeyserTimes Grand info could be because it was never entered in the first place. That would seem to be the case, as there are a few non-electronic records during those years. But the electronic times never duplicate the observed times. That implies that the electronic records are incomplete. In any case, I are confused, and maybe what is going on with the electronic records needs to be clarified.
