8712 16 Jun 2018 @ 0912 --- JarnoO Large, sustained preplay made me think OF was going to start. It didn't.
7964 02 Apr 2018 @ 1140 --- Kevin L Snow was so heavy OF area was totally a whiteout on both streaming and static cam
7955 08 Mar 2018 @ 0643 --- DaveM This eruption was a long duration 3m10s
7817 09 Nov 2017 @ 0632 --- JarnoO Appears to be post-eruptive. Runoff channels steamy. Temperature as of writing 23°F.
7798 30 Oct 2017 @ 1017 30 Oct 2017 @ 1018 JarnoO Strong preplay, which could've resulted in an eruption.
7283 25 Sep 2017 @ 0924 --- Kitt B preplay, so previous eruption was a short
6996 23 Sep 2017 @ 0632 --- JarnoO ~45s strong preplay which usually results in an eruption. No eruption followed.
5071 19 Aug 2017 @ 1817 --- Graham Really big and long preplay that would normally start the eruption.

4120 23 May 2017 @ 0513 --- JarnoO Was pre-eruptive spouting. Likely went before 0530.
3270 09 Jul 2016 @ 0246 --- JarnoO 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 --- JarnoO May have erupted during early (0216-0225) nightly reset of the webcam. A lot of pre-eruptive spouting just before the interuption.

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.
