It was foggy in the Lower Geyser Basin, and we arrived by bicycle at Great Fountain while it was in eruption, probably the third series of bursts. Knowing the time of an eruption, decided to attempt to see the next eruption that evening.
In the afternoon, went out ot Grand as the weather was getting worse. Fortunately, and despite a long Turban Delay Interval, got to see the One Burst Grand eruption before the rain.

The forecast storm never really materialized, so by 19:00, went back to Great Fountain. Arrived to find the water level in the crater out of sight. Over the next hour, as the sun set, the water level would come into sight, only to sink again. After sunset, the overflow had not yet started, so we decided to head back instead of waiting at least another 1-1/2 hours.
The sky had cleared by the time Grand was due to erupt. Waited for an hour's worth of Turban eruptions, then got the One Burst Grand eruption that lasted less than ten minutes. But as we were crossing the bridge, Castle started erupting. For once, a Castle eruption with the moon in the proper location resulted in a major eruption with full arc moonbows starting about the time the eruption turned into steam.
