2017-11-14T09:31:09 --> 2017-11-14T10:41:09

2017-11-13T11:00:09 --> 2017-11-13T13:00:09
A mini eruption from an on-disk coronal hole.

A mini eruption from an on-disk coronal hole.

2017-11-12T09:10:09 --> 2017-11-12T19:40:09
A filament eruption was observed at the west limb. There was also synchrounous activity observed near the west limb. The eruption seems in two-steps: first, the flux rope slowly raised up, then it erupted abruptly.

2017-11-10T05:00:09 --> 2017-11-11T01:40:09
A large-scale filament eruption from the NE. The filament at the limb is more evident. But the on-disk part of the filament eruption can be seen through coronal emission variation after the eruption.

2017-11-14T06:31:49 --> 2017-11-14T06:44:40
Small spray in AR 12687

2017-11-08T11:00:09 --> 2017-11-08T20:30:09
A filament eruption was observed near the east limb.

2017-11-21T07:00:09 --> 2017-11-21T13:00:09
Although the filament/prominence material seemed to largely move northward to lower heights, the overlying corona was also found dimmer in the direction of 9:30 or so. This event was responsible for a CME with a spiky front (see http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20171121.121207.w045.v0089.p080&frame=34&r).

2017-11-17T00:00:09 --> 2017-11-21T13:00:09
AR 12687 was a generally inactive active region. Some time on 19 November 2017, it became spotless. Coronal emission remained, however.

2017-11-21T01:52:01 --> 2017-11-21T02:50:25
A minor eruption was associated with a B1.7 flare in an unnumbered region (no sunspots). Subsequently large scale loops to the north were disturbed, but the disturbance did not seem to go beyond the northernmost footpoints of such loops.

2017-11-20T12:25:13 --> 2017-11-20T13:11:13
Minor eruption from a region ~20 degrees behind the east limb (based on STEREO-A EUVI data).

2017-11-20T13:00:09 --> 2017-11-20T20:00:09
At a high latitude region in the northern hemisphere, large-scale brightening was seen, which was probably a post eruption arcede. There was a filament eruption northwest of the brightening area, but it is not clear it was related.

2017-11-16T12:00:09 --> 2017-11-17T03:00:09
A slow eruption from the quiescent region south of AR 12687. A diffuse filament is seen to slowly erupt southward around 1900 UT, resulting in a spreading ribbon.

2017-11-18T21:40:13 --> 2017-11-19T05:00:13
A flux-rope-like structure erupts slowly over the west limb. This is so diffuse that it is seen only in difference images, in 171 A in particular. It may not have escaped the Sun since there was no CME.

2017-11-18T13:50:25 --> 2017-11-18T14:26:25
Another diffuse jet seen only in difference images. No untwisting motions may be seen.

2017-11-17T00:10:14 --> 2017-11-17T01:15:02
The flare occurred in the southeastern periphery of AR 12687. Around this time the region still consisted of beta spots whose area was 90 MSH. The flare was accompanied by a jet.
