Post-eruptive with steaminess around cone gradually diminishing. Guessing ±0615 as eruptive time, given the silhouette of ±passive steam becomes only visible at 0624 on static. |

(wc) Post-eruptive based on lack of activity and steam plume in the following minutes. As cam panned over @ 1804, the cone itself appeared steamy as well, which decreased in the minutes that followed. |

One frame with very large preplay. Subsequent frames show nothing and at 0919 it completely fogged in. When fog had cleared @ 0943, all that remained was a lightly steaming cone. Makes it plausible that 0911 was a large false start inducing preplay delay. |

This is my first time on the site. I live in Dubai, hence the odd time of this note. I was looking at the ABC News Live cam, which is not so live, and came here to find out when the next eruption of OF might be. Then is seem strange that there is no reported eruption for over 4 hours. Is it because no one reported one? |

Electronic temperature trace for the afternoon/evening has no spikes. Probably caused by an ice dam diverting the runoff. |
