A good day to do something other than watch One Burst Grand Eruptions. Since the parking was surprisingly easy, stopped into Norris to watch New Crater/Steamboat for half an hour. Nothing to get excited about that I could see.
Did go out after sunset. Looked like West Triplet had finished erupting recently, which could mean Grand would wait the two hours for the next West Triplet eruption. Got the expected early Turban delay interval, but Turban was strong and sustained. It was just light enough to see Grand booping well after the two minute mark, so the start of Grand's eruption wasn't a surprise.
The first burst lasted 7-3/4 minutes, so not surprised that there was a second burst. The surprise was that the second burst lasted less than a minute, and at that point the whole eruption was just over nine minutes long. The third burst made sure that Vent & Turban would quit, and fairly quickly. West Triplet did nothing during or after Grand's eruption.
