4108 20 May 2017 @ 1715 --- Tara No eruption as of 1635...left due to hail storm. Maureen stayed until 1715, still no eruption as of that time.
4104 20 May 2017 @ 0725 20 May 2017 @ 0740 RLJones No water visible in FTN, Morning, or Spasm. Clepsydra steady. No activity in Twig or Jet
4099 16 May 2017 @ 1500 16 May 2017 @ 2113 RLJones Bryon arrived at FTN at 1500, I arrived at 1655. We did not see each other until about 1807 and then began coordinating our observations. From 1500 until the FTN start at 2042, Bryon observed 24 stop - restarts by Clepsydra. From 1655 until the FTN start at 2042 I observed 9 Clepsydra stop - restarts. In the stop - restarts, when Jet started to erupt the boiling in Spasm decreased and Clepsydra stopped. When Clepsydra restarted Jet stopped and the Spasm boiling increased. At 1804 Jet started to erupt BUT Clepsydra and Spasm this time CONTINUED to erupt. After 1804 the seeming correlation ended and Clepsydra no longer appeared to affect, or be affected by Jet. Twig was on very frequenty from 1655 until I left at 2113. The Jet eruptions were very weak until just before the FTN start. Superfrying pan erupted at 2035 & 2040, just before the FTN start with some burst to 10+ft There were two short bursts from MT. The 2044 Bursts were to about 10 feet and the 2048 bursts to about 25ft. FTN stopped at 2109. When I left at 2113, Twig, Clepsydra, and Jet were still erupting. When Byron arrived at 1500 the Fountain area was dry and he guessed that the last FTN eruption happen 1 to 2 hours earlier. It was 5 hrs 42 minutes after Byron's arrival that FTN finally erupted at 2042. So, the interval had to be possibly 7 to 8 hrs or more. Note sure how this fits into the other Geyser Gazers recent observations, but it did make for an interesting and strange evening for the two of us.
4089 12 May 2017 @ 1902 --- Tara Away from Fountain from 1720 to 1902. Upon my return Spasm and Jelly were full, Twig and Peanot were dry, and Clepsydra was steady and strong, no pausing. Fountain and Morning maintained their high water levels.
4088 12 May 2017 @ 1622 12 May 2017 @ 1720 Tara Arrived at 1622 to find Twig and Spasm erupting, Jelly overflowing, Fountain and Morning at high water levels (18-24 inches below rim and "breathing"), Clepsydra pausing and restarting on a 5-7 minute cycle (pauses lasted 1-2 min), and Jet erupting every 8-10 minutes. Twig stopped at 1639. Seems very similar to behavior described by Steve C, Jim S, and others on the afternoon of May 5. I also saw similar behavior in November 2015 and October 2016.

Spasm full and erupting, Jelly full, Jet grumbling and erupting at short, irregular intervals. Clepsydra was starting and stopping every 3-4 minutes until 0940 when it turned on and stayed on.

515 28 Sep 2012 @ 1800 28 Sep 2012 @ 2000 Jake didn\'t see a steam cloud from GF @ 1900, observed Twig late ie @ 2000...guessing Fountain went @ 1800
473 17 Sep 2012 @ 0940 17 Sep 2012 @ 1045 Maureen Erupted after 0940 and before 1000. Too foggy in basin to see steam cloud and when I went back up, Twig was in eruption at 1045.
379 04 Aug 2012 @ 2325 05 Aug 2012 @ 0000 Maureen Erupted at 2325 last evening. Did not stay for the duration.
364 23 Jul 2012 @ 1600 --- Maureen Twig ie at 1600, walked up to see what happened and it looked like Flountain had erupted before 1500 if I had to guess. Shorter intervals maybe?
