GeyserLog 4.1

GeyserLog 4.1 is available on the iOS AppStore.

Functionality remains the same, but much of GeyserLog has been rewritten to use newer features of iOS such as SwiftUI, Swift Concurrency and better networking.

  • Logbook List replaces the old Logbook view and the Recents list. It allows for display by name or event time over a selectable period of time. Filtering by groups and features is supported. Events use color coding and icons to differentiate between eruptions, notes, webcam and SMS entries, and your own submissions, along with icons to denote comments, confirms, and attachments.
  • In the Logbook, when a note is later than the latest eruption event, both will be shown.
  • Formatting of messages for Satellite SMS (requires registering your phone number with the GeyserTimes website.)
  • The Predictions view will now include the Apple Weather for the same period of time.
  • Predictions within an event panel will use the same color bar format, along with a display of the window. The feature name will also be highlighted with the color bar value if applicable.
  • Notebook Pages allow the gathering of notes and event times that don't need to be submitted to GeyserTimes. It's still a work in progress, and the views will probably change as field testing progresses. Also, it's not guaranteed to not lose data, so use with caution and please report any failures or problems.

Observations for 2025 June 14

With all the longer intervals recently, decided it was time to push back my Grand window, especially for nighttime activity. Went out at around the seven hour mark, just as the moon in a clear sky was rising above the ridge.

Still ended up waiting almost an hour for the One Burst Grand Eruption. There was a several second long False Pause at around the 8-1/2 minute mark, then the first burst continued for almost three more minutes.

Observations for 2025 June 13

It appeared that Rift erupted overnight, probably before midnight. Unlike yesterday, West Triplet did not eruption during the several hour wait at Grand, and never appeared to show wter in the vent.

Grand itself had a Turban Delay interval at our arrival. We finally got a One Burst Eruption two hours and six Turban eruptions later. The eruption was nicely backlit with what little wind pushing the steam to the north.

Afterwards went to investigate the progress on the boardwalk between Oblong and Giant. For a week, it seemed like nothing much, about 50 feet of new walkway. At least it looked like the new walkway is solidly built and won't immediately get bouncy like the old walkway.

The dumpster in front of Grotto was gone, replaced by one that gouged the paving material. Will be interested to see if there is any attempt to replair that damage.

Was surprised to see a second crew working on the Fan & Mortar walkway (the Oblong crew is on their weekend), where they were removing the old plastic walkway and replacing it with the newer boards.

Did a quick visit to East Sentinel, where it appears to be back to what I've considered its normal activity, with the murkiness gone.

In the afternoon it was a windy wait for Grand. Once again, I may have arrived during a Turban Eruption Delay. If so, this time it was six Turban eruption intervals before the One Burst Grand Eruption. We also got West Triplet ending just before the Grand eruption.
