Observations for 2026 June 04


With a short interval eruption in the middle of the night, didn't need to go back to Grand until mid-morning. Only waited about an hour before West Triplet started. That was quickly followed by the One Burst Eruption. The one notable thing about the eruption was that it took Vent over four minutes to get started.

After the eruption ended, I stuck around to see either West Triplet end, or Rift start. It was the latter, which started shortly before Beehive erupted. I caught that eruption from over by Castle.

Spent a couple of hours in the Bijou Cage. Bijou was pausing for about 75 seconds every 22 or so minutes, except at one point there was a 13 minute interval with a corresponding shorter pause. Then a 22 minute interval with a 2-1/2 minute pause. I didn't see anything from Mastiff during that time.

Emerald was rising and falling regularly, about ten minutes at the rim, bubbling slightly, then ten minutes out of sight. Giant had some nice cone filling vertical surges that got up as high as the top of the bite on the right side.

Late afternoon was partly cloudy and breezy at times. Without the sun out the wind made it almost uncomfortable, and the changes meant it went from underdressed to overdressed. Fortunately there was no rain and the wait was short.

I did see one complete Turban eruption interval before Grand filled nicely around 17 minutes, started having waves that built in intensity, then erupting at around the twenty minute mark. Once again, it took Vent nearly four minutes to start, which is much longer than I am used to seeing.

West Triplet started a few seconds before the first burst ended, then we a nice second burst that lasted over a minute. The West Triplet eruption was not followed by Rift, but Sput C1 was again active. At this point I think the sput will be a regular feature of those eruptions.

Got back out to Grand about an hour before midnight. Within that hour we got a West Triplet eruption and a Turban Delay Interval. Most likely it would be several hours before Grand would finally erupt, so we headed back in just after midnight.
