Missed another nighttime Grand due to the weather, so got an early start on Grand based on that double interval. It was one of those starts were Turban goes on for well over a minute before Grand joins in.
During that eruption got an announcement that there was an even at Fan & Mortar. Not just the usual single blip from the Main Vent, but frequent splashing in Main along with high surging Lower Mortar and small, short eruptions from Bottom Vent. When the Fan vents did turn on, for a couple of minutes it looked like we might get an eruption, but then Gold turned steamy and the wheezing, knocking sound started. One that, to me, signifies nothing is about to happen.
In the early afternoon got a short Rift, followed by a wait of several hours for Grand. Nothing much to get excited about, other than it was adding to my new one burst streak.
The early night eruption of Grand, however, was different. The sky finally cleared out and the moon was bright and low to the west. Didn’t have to wait one Turban eruption interval before Grand started almost immediately after Turban did. The first burst lasted only 8m10s, which would probably have been a record for short one burst eruption. So fairly confident that there’d be a second burst. It was a long one, 70 seconds long, so figured that we’d seen the eruption. So the third burst was a distinct surprise following a pause that lasted almost a minute. For this eruption, Grand had reverted in behavior by about twenty years.
