Not seen on the overnights at all, even in clear weather. Guess it really doesn't like snow. |

Has recovered from the long (>4h) intervals during the daytime hours of January 27. Seems even 3h00m±15m would suffice now. |

Plate's intervals have abruptly lengthened overnight compared to the currently typical 3h00m±30m, starting with 0026 wc (I=4h06m), previous interval ±3h29m (it could be argued that that one was the start of the lengthening - the one before was ±3h at most given the unclosed interval). The next one, 0435 wc, had an interval of 4h09m and the most recent one of 5h36m. Could be it's nearing the end of an active phase, not to be seen for days to weeks. Given past intervals, it appears certain it's done that repeatedly since reactivation early 2022, so it's not out of the ordinary. |

Bubbling as I passed by. No eruption by the time I left the hill around 2000. Guessing it's in the 'bubbling for hours' mode. |
