Observations for 2025 May 28


A report at 0500 of Vent & Turban in eruption let me know that the overnight Grand eruption was somewhere around 0400, and there was no need to rush out.

Got out to Grand just in time for a Turban Delay interval which included a nice boop from Grand. Went down to check on Economic, and it was about 2cm below overflow, but still convecting slightly and it was wet all around the outside of the rim.

The Delay at Grand only lasted four Turban intervals, and the One Burst Grand lasted almost 11 minutes. West Triplet was overflowing heavily after the eruption, but I didn't see any splashes or feel any thumps.

Was intending to go out to Geyser Hill as it was probably time for Beehive, and spend some time at Aurum. That was when I heard the report of Aurum erupting. So instead waited maybe 45 minutes for the start of Beehive's Indicator. The conditions were excellent, with some wind but not enough to matter that close. The duration of the eruption was longer than typical, at 5m16s.

It was a short wait for the next One Burst Grand eruption. Nothing much to say about it, other than it lasted almost 11-1/2 minutes. It was followed by a few splashes from West Triplet.

Afterwards caught the start of Sawmill, and then stuck around for about 1-1/2 hours hoping to see Uncertain erupt. Instead decided to leave when Castle started. With the sun low, there were some strong rainbows, along with a curtain of mist across the bike trail. (Uncertain finally erupted just after we left Castle.)
