In mostly short cycles this afternoon following the event cycle. Weak water levels. Two cycles where the water levels shot up, but only for a couple minutes instead of the prolonged strong activity thing we have been seeing every several hours. |

Saw two decent cycles today both had main vent splashing 30 minutes into river with good/variable water, neither of the cycles water levels looked good for long, otherwise F&M has been in short cycles for
a lot of the day |

Fan and Mortar appear to be having mostly regular cycles based on periodic observations this morning and afternoon. Angle has been turning on and off mostly at the expected times and is not perpetual as it was much of last summer. |

Sat a while this afternoon. Angle wild phase continues with short cycles and not much in the way of bottom vent or water levels. Did get a bottom vent / lower mortar water cycle with a 30+ minute off at 1924 with G taking ~4.5m to turn on, but not a lot came of it when it counted. Still wondering whether anything even matters right now, or whether it will just spontaneously decide it's time. |

upon arriva, River, High, Gold and Angle were all splashing. H 2 - 5' at times. Angle disappeared for 8 minutes or so and H and G kept erupting with variable levels. Deep and loud rumbling from Mortar. I don't remember it being so loud in years past but could've been. By 2320, Mortar was much quieter and Angle alone was schczing schcz ... schcz .. schchcchcz. Unattended. |

Are you a gazer? Do you find event cycles too exciting? Love angle? Then this interval is for you. Nothing encouraging seen today as of yet water levels have been uninspired. |

Fan's minor vents on from 1205 to 1250, Angle continuous after River shut off. Low water in Bottom at 1305, runoff channel bone dry other than a couple small puddles just below BV. Runoff channel with lush bacterial growth next to Angle looks mostly unchanged. River back on at 1310. |

F&M was quiet about 1100 when I passed to look at Morning Glory. On return about 1108 Bottom vent was active and was occasionally joined by Lower Mortar. River came on about 1110 and the first splash seen in Main Vent was at 1112. For about 20 minutes there were occasional splashes in Main Vent, River was turning on and off and on and off. No activity from High or Gold. After AJ arrived we walked away and were about 2/3 of the way to Castle before AJ called F&M. All of this occurred in blowing snow storm. Sigh... |

Possible eruption time, ie, at this time. Steam coming from the right location (mostly right location at least), steam drifting in from the right. It is a possible eruption but due to the darkness, as well as the possibility of this being a post eruptive Grand, I am leaving as a note for now. |
