2012-03-17T20:10:12 --> 2012-03-17T22:20:12
A minor eruption in the AR produces a coronal EUV wave propagating through a fraction of the visible disk.

2012-03-17T07:40:12 --> 2012-03-17T10:36:12
A surge/jet on NW limb.

2012-03-16T17:30:00 --> 2012-03-17T00:20:00
A polar crown filament embedded in a coronal cavity on the NE limb.

2012-03-16T17:30:00 --> 2012-03-17T04:40:00
Two successive filament eruptions took place one after the other. The two filament channels are parallel to each other. There is a likely causal connection between the two eruptioins, similar to that reported by Schrijver & Title (2011 JRG) and simulated by Torok et al. (2011 ApJ).

2012-03-16T02:30:12 --> 2012-03-16T06:20:12
Brightening along transequatorial loops, likely due to a small-scale flare or injection of hot and dense material into these loops.

2012-03-15T20:20:00 --> 2012-03-15T22:54:00
A prominence on the west limb erupted and seemingly kinked or writhed, then disappeared. However, hotter material seen at 211 continuously erupted.

2012-03-14T22:30:00 --> 2012-03-15T02:30:00
A loop prominence on the east limb, exhibiting dynamic flows and drainage. It was depleted within ~4 hours of the duration of this movie.

2012-03-14T22:30:00 --> 2012-03-15T02:30:00
Multiple surges, similar in morphology, repeated occurred. Two episodes took place within 4 hours. The first one was rather mild, with most material falling back. The second one was more violent and much faster, exhibiting helical threads.

2012-03-14T07:40:04 --> 2012-03-14T09:01:04
Surges returning along curved trajectories on the east limb, likely falling along magnetic field lines.

2012-03-13T23:00:04 --> 2012-03-13T23:40:04
One of the multiple surges from this AR showed unwinding motions, seemingly unwraping itself. See another example observed by Hinode/SOT (W. Liu, Berger, Title, Tarbell, 2009 ApJL) at: http://adsabs.harvard.edu/abs/2009ApJ...707L..37L

2012-03-13T23:00:04 --> 2012-03-13T23:40:04
A small-scale surge on the SW limb, causing flaring-like brightening at its top.

2012-03-13T23:00:04 --> 2012-03-14T06:20:04
Multiple surges from AR on west limb shooting in different directions.

2012-03-13T23:00:04 --> 2012-03-14T06:20:04
Two nearby polar crown prominences erupted one after another in a few hours. The first one seems to be largely located behind the limb.

2012-03-14T15:10:04 --> 2012-03-14T16:20:04
An eruption/flare occurred from the AR near the disk center, ejecting material directed toward the earth. No halo CME reported to be associated with this event.

2012-03-13T17:05:04 --> 2012-03-13T17:50:04
Running difference version of the global EUV wave event.

2012-03-13T16:05:04 --> 2012-03-13T18:30:04
A large-scale coronal EUV wave was generated in association with the M7.9 flare and a fast CME (1900 km/s measured by LASCO). The precursor to this large eruption was a smaller eruption, a bulging volume toward the southwest of the active region, starting at about 16:05. The main eruption occurred at 17:05.

2012-03-13T10:50:04 --> 2012-03-13T11:10:04
A moderate-sized surges on the eastern hemisphere occurred at about the same time as a large-scale surge on the western hemisphere. Could there be any physical connections between these two remote events, like in sympathetic flares?

2012-03-13T10:50:04 --> 2012-03-13T11:10:04
A surge from the core of an active region near the northwest limb.

2012-03-12T09:20:04 --> 2012-03-12T10:30:04
Two small-scale surges occurred on SE limb almost simultaneously.

2012-03-12T08:40:04 --> 2012-03-12T17:00:04
A 304 prominence appears on the SE limb, exhibiting rotations, accompanied by swirling motions of 171 loops, mimicing coronal cyclones recented discovered by AIA (see Zhang & Liu 2011 ApJL, http://adsabs.harvard.edu/abs/2011ApJ...741L...7Z)
