Once again I waited less than a Turban eruption interval for the Grand eruption. It had lightened up quickly, and I was planning to set up the camera except the Grand eruption came first. I have now seen four eruptions of Grand with two bursts in the last four days, compared with seven over three weeks prior.

Attempted to see an eruption of Great Fountain again, without success. Were way too early and the winds were just beginning to start up, so returned.

Eventually headed out to Grand. The wind wasn't up to Iceland levels, but was still enough to make sure everything didn't blow away, and cooling enough to require a jacket. Arrive to an early eruption of West Triplet. When it ended without a Grand eruption, knew we were in for a long wait.
A fifteen Turban interval wait. The intervals slowly got shorter. At one point we had an interval of less than 15 minutes, only to be followed by a couple of intervals of more normal length.
West Triplet started erupting again, and Grand finally looked good early, and didn't drop. The One Burst Eruption tried to pause at around the eight minute mark, without success. Then after 9-1/2 minutes, we had a false pause, followed by a few more seconds of jetting from Grand.

An eruption of Rift followed, and I didn't wait around to get the duration of West Triplet, which by then was well over 45 minutes.
