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).

AR 12687 was a generally inactive active region. Some time on 19 November 2017, it became spotless. Coronal emission remained, however.

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.

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.

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.

Another diffuse jet seen only in difference images. No untwisting motions may be seen.

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.

Last of three small eruptions observed within a 4-hour period. The SG slit covered each at a different stage of the eruption.

This is the long and narrow coronal hole seen over the previous days. As the sun rotates this coronal hole seems to be an extension of the north polar coronal hole.

A coronal hole (dark region on the North East quadrant of the solar disk) is accompanied by two filaments running parallel to it at higher latitudes. As the time goes by, the high-latitude filament erupts folllowed by the one nearest to the coronal hole ~10 hours later. No CME was identified with SOHO/LASCO; therefore, the eruptions were not ejective but rather contained in the low solar corona.

Unwinding maybe. Seen in both Si IV and Mg II SJ. Full readout.
