Water level in Clepsydra’s side vent (CSV) visible but pool is not completely full. Estimated time of most frequent Fountain eruption is about 1-1/12 to 2-1/2 hours ago based on other observations made over the past two weeks of the relationship between the water level in CSV and Fountain’s eruptions. |

Arrived around 13:30 to find Clep pausing frequently and high water levels in Fountain and Morning. We all thought the behavior was odd, because we thought Fountain's interval was approaching 8h. Found out later that Fountain went short and erupted just under three hours before we arrived. Mystery solved. The Fountain group was in a stall for most of the afternoon. At 14:49, Fountain had water within a foot of overflow. Noted at 16:07 that Fountain appeared to be dropping. Water was high in Morning the whole time, and we did note convection at 14:37 as well as some bubbles later on and throughout a lot of the afternoon. Clepsydra was having long, frequent pauses early in the afternoon, the last one I noted started at 14:33. Jet was not in series as far as I'm aware when we arrived, but the activity slowly picked up throughout the day. Several Twig's - though I only noted one at 14:28 - and activity from other features. We first noticed bubbling in MT at 15:14. That eventually progressed to a boil, and an eruption at 20:28. We left after that.
Just as we were about to go behind the trees driving away, saw Fountain's steam column start to rise. 20:42, likely ns. We went back to take a look. Just Fountain, with a beautiful sunset in the background. Could have been more MT's, did not stick around for duration. |

It appears that fountain went off very recently. Both F and M are steaming, no water in Morning. Channel between F and M very wet. Frost on boardwalk except near F where there is water. Clepsydra is in full eruption.

When I arrived at Fountain it was in a stall. Jim H. Was out about an half an hour before me and saw the same thing, Clep and Twig on and off, the water in Fountain and Morning was high and easly visable from the boardwalk,. Clep finally turned on and stayed on at 1626. After that the water levels in Fountain and Morning dropped about 4 inches and stayed at that level untol I left at 2000 with no eruption. |

Clep was on when Kathy arrived. Spasm was full and erupting. Water levels in Fountain and Morning were barely visible. Clep and new vent have been cycling on and off since then. water levels in Fountain and Morning have risen substantially reaching into the neck and about 2 feet from the rim of Fountain at 2000. Jet has been active while observed with first @ 1851. Spasm has been erupting constantly while under observation. Twig @ 1958. New vent is throwing rocks out of the crater onto the platform. Nothing from Super Frying Pan as of 2022. 2035 water in the new vent changed from 1 - 2 ft water based broad eruptions to more of the jetting steam based eruption and the water in Fountain dropped 6 - 8 inches. Twig end and drained @ 2045. no eruption as of 2114 when we left. |

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. |

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. |

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. |

From the observation deck: Twig was dry, peanot water was 3/4 full and bubbling, no visible water in Morning or Fountain, Clep on, SFP ie @0820. Looks like the "shelf" on SFP is still intact. |
