Giant Hot Periods 1988


In October 1987, the first Giant hot periods since 1955 were observed. They started about six weeks after the 1987 Sep 12 eruption. More hot periods were observed in the spring, with the next eruption of Giant on 1988 Jun 28.

More hot periods were observed in late July, just as the fire activity in the park started to pick up. By late August 1988, Giant was having hot periods almost daily. All of us had no idea what to look for or what was the progression of events leading up to an eruption. Notice the confusion over which vents are which, and what they should be called. Also notice also how excited we could get over what we now know are pretty minor hot periods.

As it turned out, there wasn't much chance of observing Giant due to the fire activity, and the evacuation of the Old Faithful area. Giant did erupt just a week after the last hot period on this video, on 1988 Sep 12.

1983-1986 New Crater/Steamboat Geyser Minor Activity

The New Crater Geyser also has a second official name: "Steamboat Geyser". I prefer the first name officially given to it in 1930. It's so much more descriptive and bureaucratic.

Update: 2018 May 30 Added a 1984 superburst, and appearance two days after the 1983 May 24 eruption.

GeyserLog AppleTV 2.0


The GeyserLog AppleTV v2.0 app is now in the Apple App Store.

This major change in this update is the inclusion of the display of GeyserTimes predictions, and the display of notes and comments. It also includes more filtering options, and the usual display cleanup, bug fixes and crash elimination.

The app is not free. The price helps pay for the costs of software tools and graphics tools needed for app development. Geyser gazers are welcome to contact me and get a Promo Code which will allow downloading of this app, and the iPhone/iPad app for free. I'm also open to suggestions for features users would like to see added, or bugs that need to be fixed.

GeyserLog 2.2.1


GeyserLog 2.2.1 should now be available in the Apple App Store.

The biggest change is with predictions. They are working again, and I've added a way to either show all predicted features, or just the ones you've selected and added locally. List of all predictions can also use NPS or GeyserTimes as the source.

Also added is the ability to display event comments. This can be controlled from the Settings view, in case the tendency to emulate the worst of Twitter becomes too annoying.

There's also lots of the usual display cleanup, like using a mono-spaced digits font to stop the jumping around in various timers.

The next update will be to the GeyserNotes AppleTV app, where support for predictions will be added back in, along with whatever bug fixes I can make.
