Latest Notes

Note IDStart TimeEnd TimeEntrantNote
3270 09 Jul 2016 @ 0246 --- DGInc Looked like it was in a post-eruptive phase. Definitely went during nightly reset.
3220 06 Jul 2016 @ 0207 --- smousley 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?
3141 27 Jun 2016 @ 0216 --- DGInc May have erupted during early (0216-0225) nightly reset of the webcam. A lot of pre-eruptive spouting just before the interuption.
2935 01 Jun 2016 @ 2017 --- MikeG Forgot to write down eruption time. It might have been 20:17, and short duration.

2870 21 May 2016 @ 2248 --- DaveM Old Faithful erupted. But since "eyes in the basin are most often more reliable than eyes through the webcam" I hope someone in the basin saw the eruption.
2643 02 Jan 2016 @ 0629 --- Joethermop OF really fogged the area could not see eruption 0610-0615?
315 22 Jun 2012 @ 0546 22 Jun 2012 @ 0552 Loisb I have OF starting at 0546 per the UB cam and it was a long. I also have Lion starting at 0552 which would make it an initial

88 24 Jan 2012 @ 1250 --- ofcarolyn Park employees are downloading Old Faithful\'s temperature logger near 12:50 p.m. today.
727 19 Jan 2012 @ 1200 19 Jan 2012 @ 2359 WillBoekel Electronic temperature trace for the afternoon/evening has no spikes. Probably caused by an ice dam diverting the runoff.
