Clepsydra on steady now, so this will likely be another 2 to 4 hours for Fountain to erupt. |

The sinter around Fountain is wet. Twig was Ie, Jet was weak. And Clepsydra shut off, so perhaps Fountain just finished. No water visible in Fountain even if I stand on the fence. |

Had not yet erupted when I left at 1530 after Clepsydra resumed continuous activity, which gave a probable prediction window of 1730-1930. |

Fog has cleared. Water level in Fountain is high enough to indicate Clepsydra had an extended period of pauses following the previous eruption of Fountain. |
27660 |
17 Aug 2023 @ 0650 |

LynnS |
Puddles around Fountain and the area of Fountain’s runoff are not steamy. Too foggy to determine water level in Fountain. When viewed from the top of the stairs, the water level in Morning was visible but not very high. |

What with one thing and another, I think what happened was we missed an early afternoon eruption, after which we got a stall with possible eruption around or shortly after sunset. |

Both Fountain and Morning have now dropped, Fountain 12-15 inches below rim {got as high as 6-8" below rim}; a little harder to judge Morning due to late afternoon light. Thief still fairly full and "simmering;" Jet on but irregular, Spasm still erupting; Clep on strongly and consistently, still no SFP. |

And we're all confused. Fountain now visibly filling with convection over vent, Morning a bit fuller, nothing in MT, Jet steaming and gurgling, nothing in SFP, Jelly quite full and hot, Spasm just filled and started bursting. This has been you 5 o'clock Fountain report... |

Clepsydra in pause mode; puddles around Fountain are not steamy; Spasm not erupting, crater is half full with blue water; Jet rumbling; steam makes it difficult to be certain but I don’t think water levels in Fountain and Morning have risen; no water visible in CSV.

Spasm was ie, Clepsydra was turning on and off, Jet was active, SFP had just finished and the water levels in Fountain and Morning were high. However it was about 25 degrees with a 20-25 mph wind. So I decided a hot chocolate run was in order. |
