(wc) Already post-eruptive based on no preplay seen as of writing (1102), with the cam having been on Old Faithful since 1039. No OFVEC static archives (not to mention it's been very spotty ever since streaming came back up), so no indication when the eruption occurred. |

(wc) Large play (±10s each) which is normally seen only at the start of an eruption at 1100, 1121 and 1132, the latter the biggest by a mile. Additionally, 1104 and 1114 were smaller than the aforementioned, but these also lead to an eruption in the majority of cases. Cam panned away at 1136, at which point the interval was already at 2h08m. |

(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? |

May have erupted during early (0216-0225) nightly reset of the webcam. A lot of pre-eruptive spouting just before the interuption. |

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