Billowing steam with frequent splashing (5-15' or so over the top of the cone). Logger is having trouble reading majors vs minors right now, but I believe Art-P's major observation via the webcam. Castle looks remarkably like it did post-major in late June 2021, when its intervals became long and irregular. |

Castle erupted 2258E last night. Graph looks like a long minor but in the basin it looks like it majored overnight (billowing steam, no splashing or spritzing). Probably a major, but unclear. |

Just an odd note, I looked at the temperature monitor for Castle and there was no other eruption on the temp monitor recorded between the 0759 eruption on the 3rd and the 1011 eruption today on the 4th. I’m not sure what to make of it. |

The graph barely picked up the eruption, if the small spike on the graph was an eruption. I think the graph is somehow wrong because I don't recall Castle having 12.5 hour intervals. I'll erase the entry when more data is available. |

After reviewing the castle logger graph several times, castle had a minor. The duration of the eruption was 12 minutes. I lined up the start of the spike on the graph to the end of it. The spike on the graph is small compared to the rest of the previous eruptions. |

From Beehive, sounded like steam phase of eruption. Perhaps major after minor? Anxiously waiting for electronic. With last moonlight looks like eruption. |

Duration was 4 minutes. Geysertimes chose a less complete entry submitted 7 minutes after the eruption over a webcam entry. I find the bias of the software disturbing. A more complete entry should be listed as primary whether is is submitted immediately or much later or if it is seen in person or on the webcam. |
