Observations for 30 June
Lately Grand has been having a long interval followed by a couple of shorts, or some sort of variation on the theme (like two longs in a row, or three shorts, etc.) Today it tried something different. The early morning interval was a long, so I expected a short. Instead we got one of the longest intervals of my stay. It seemed to break all the rules. We had a false Vent overflow, West Triplet erupted a second time without Grand following along, and had several short (under 17 minute) Turban intervals, and Grand finally initiated the eruption for The Burst and Quit. It was a hot day and fun was had all around.
At least it kept to form for the nighttime eruption, with a little over seven hour interval putting the start in the second minute of July. But what I don't understand is why tourists come out on a moonlit night and then proceed to wave weak flashlights at the eruption. Fortunately the moon was so bright that they didn't matter.
