Overnight the webcam picked up a Grand eruption at just over the six hour mark. So was out at dawn just in case there was another six hour interval. There wasn't, and instead ended up waiting over four hours through a couple of West Triplet eruptions. The second one resulted in the start of Rift. The wait started out overcast and foggy but above freezing. The sun tried to come out, but never really did.
It was a typical non-delay type of long wait. During the last couple of hours of the wait, Turban's eruption intervals got shorter. There were several below 17 minutes, and the Turban eruption duration prior to Grand's eruption was less than two minutes long.

During the last hour of the wait the showers started, and then there were showers all afternoon, so it seemed like a good time to do some app bug fixing.
After an afternoon of occasional thundershowers, headed out to cool gray skies. The hour-and-a-half wait was uninteresting until the end. At around the 18 minute mark after the previous Turban eruption, Grand's pool, which had been looking poor, started to rise. For the next ten minutes the pool was at or near full, but never quite good enough. Then the pool surpassed the level from the previous fills. Vent overflowing and a series of boops and then we got another One Burst Eruption. As before, it seemed like Grand slowed down around the eight minute mark, and long ago it would have stopped at that point. Instead the jetting picked up a bit, and lasted another three minutes.

Shortly after Grand started, West Triplet also began to erupt. It seems that this year West Triplet can recover from Rift within one of Grand's eruption intervals.
