2017-12-21T19:00:09 --> 2017-12-21T22:30:09

2017-12-21T04:30:01 --> 2017-12-21T10:00:01
Slow eruption followed by mass falling back. The associated CME may be http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20171221.071207.w041.v0309.p273&frame=17&r.

This slow and diffuse eruption is best seen in 171 A images. A filament in 304 A images disappeared, and its relation to the off-limb motions in 171 A images is not clear.

2017-12-17T05:00:09 --> 2017-12-17T12:00:09
Dimming slowly developed at high altitudes in 211 A, and possibly 193 A. This may be better captured by GOES16/SUVI. There was no clear indication of an eruption, and it was not clear how the prominence to the north would have participated in it. A possibly related CME is http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20171217.091211.w033.v0152.p083&frame=25&r.

2017-12-16T09:45:01 --> 2017-12-16T13:01:01
A coronal volume expanded, following temporary contraction in the inner part. This may signify filament activation, perhaps driven by footpoint motions not seen due to foreshortening. The expansion stopped, not leading to an eruption.

2017-12-16T04:40:13 --> 2017-12-16T06:30:13
A flux rope strcture seems to have been pre-existing above the prominence. The eruption did not go through because of overlying field.

2017-12-15T12:00:09 --> 2017-12-15T15:40:09
A filament eruption was seen southeast of a non-numbered region. It led to a striking twin dimming and spreading flare ribbons. The associated CME is http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20171215.170007.w070.v0226.p130&frame=15&r.

2017-12-14T21:10:13 --> 2017-12-14T23:40:13
The eruption was associated with a B1.1 flare and from a region slightly occulted. It was loop-like, but produced a CME that was quite narrow (http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20171214.231214.w023.v0281.p081&frame=12&r).

2017-12-14T13:50:25 --> 2017-12-14T15:30:01
The slow eruption was narrow, centered in the direction of 8 o'clock. Later a post-eruption arcade was seen near the northern leg of the structure that erupted. The source region was slightly behind the limb.

2017-12-14T04:40:13 --> 2017-12-14T06:29:25
The minor eruption was associated with a short-duration B1.1 flare in a non-numbered region. As the eruption showed a counterclockwise rotation, a diffuse EUV wave was observedtoward southwest to north.

2017-12-11T00:30:01 --> 2017-12-11T01:50:01
The eruption seems to be confined, not reaching the coronagraph height. This was associated with a short-duration B6.2 flare.

2017-12-10T21:30:01 --> 2017-12-10T22:40:01
Multiple jets are seen, but the one that was ejected non-radially was traceable for a longer distance. It also contained cool material as seen in 304 A images.

2017-12-01T01:40:09 --> 2017-12-01T08:00:09
Slow filament eruption lasting several hours. It's unclear whether it's a confined or ejective eruption.

Quiescent filament eruption from behind the northeast limb.

A spray surge is observed in 1330, 1400 and 2796 SJI.

A two-ribbon flare is observed in the 1330, 1400 and 2796 SJI. The slit crosses the southern part of the flare.
