Observations for 2025 June 03


Thanks to an observation in the middle of the night, could sleep in a little longer before going out for the morning Grand eruption. The sky was much clearer than expected, but cold and windy. And still ended up waiting two hours. We finally got a two burst eruption from Grand. After the second burst ended at just over nine minutes, I thought a third burst was guaranteed. The vent drained and made no attempt to refill.

It was a day to get some housekeeping chores out of the way, but fortunately the call for Beehive's Indicator came during a lull. Over on Geyser Hill it was still cold and windy, and that wind kept shifting enough to require the deployment of the umbrella on a couple of occasions.

Later, I got to see Rift in eruption as I arrived at the Castle bike rack. West Triplet was drained by the time I arrived. Instead of the long wait, after a half hour Grand had a Turban Delay Interval of just over 30 minutes. With Rift (and Percolator) still erupting, we got a One Burst Grand eruption that lasted 45 seconds longer than the morning's eruption.
