Observations for 2026 September 03


Went out to the Bijou Cage in the early morning. It was gray, damp and windy, and I was underdressed for the occasion. About an hour after arriving, I did see a short 2-3/4 minute Bijou pause where water was visible in Mastiff for a short time. The Southwest vents spit once or twice, and the usual post-bathtub activity (Bijou roaring, Catfish and B-C Vent activity).

After a re-configure in the cabin, I headed out to Grand. A three hour wait resulted in the One Burst Grand eruption occuring fifteen minutes after West Triplet started.

After lunch, it was back to the Bijou Cage. It turned out that the Bijou pause observed earlier was the last one for the rest of the day. I spent another four hours in the Cage, and did see a number of good sized Mastiff surges, but they never lasted long, and Bijou showed no reaction to any of them. Some people stayed another three hours, well into the dark, and at the twelve hour mark, no Bijou pause.

I had left the Cage for Grand. There were a series of shorter Turban eruption intervals, and within a few minutes of West Triplet starting, once again we got a One Burst Grand eruption.
