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. |

Castle is erupting short bursts up to 1 meter, sporadically, indicative of a previous minor eruption. |

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. |
