VEC is now officially not predicting Castle. Recent intervals suggest 19 to 22h intervals without minors. Longer intervals started ~16th. |

May have also had a minor a few hours earlier since 17 hour interval is so large to this eruption. |

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. |

GOSA playback shows a Castle eruption at 0341 with a more slender steam column than the 2204 eruption. Steam column present to about 0430 at least, when visibility was lost. |

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. |

Very foggy but it looked like Castle may have been ie. Fog downbasin may have been the result of a Castle eruption since it appeared that there was a steam phase plume at 1118 and the fog cleared shortly after that. |
