Observations for 2023 August 11


Was awake, but looking for a reason to get up and moving and not finding out until the radio call for Beehive's Indicator was made. Got out in plenty of time for a concerted eruption with Old Faithful under clear, calm, fog-free conditions.

Later on went out to Grand not knowing the time of the overnight eruption. Watched a series of indifferent Turban eruptions until after about two hours there was a Turban eruption with a short durations and preceeded by little overflow from Grand. Grand erupted on the next opportunity.

The first burst lasted 9-1/2 minutes, which is the longest first burst I've seen in years. It took over a minute for the second burst to start, which again is pretty long. Nice to see that the nine minute mark is no longer an automatic indication of a One Burst Eruption.

Later spend time at Giant, just to see what was happening, which was little to nothing. Bijou was on most of the time, with occasional slowdowns but no real pauses. Just as we were about to leave, Giant had a mini-Cone Filling burst, which even put some water out of the front rim. Haven't seen that much in a long time.

Left to go over to Daisy, where the eruption was normal in every way.

Saw the next eruption of Daisy just as I arrived at Grand for the next wait. Which was short, as ended up waiting for only two Turban Eruption Intervals. The second interval looked like it was going to become a Turban Delay Interval, but came up a minute short when suddenly Vent overflowed, Turban started followed by Grand, all in a matter of seconds. The first burst ended well before the nine minute mark, so it was no surprise to get the second burst. Even though the eruption barely lasted ten minutes, Vent & Turban quit.
