2013-05-21T12:00:03 --> 2013-05-21T23:10:03
A prominence experiences first activation (as reported earlier) and then eruption while unwinding itself.

Five eruptions from the neighborhood near the northwest limb occur in a row within a day. Each eruption occurs in a slightly different location and generates some EUV waves of various extents. It is possible that there are some causal relation among these eruptions, like sympathetic flares or the global connections (Schrijver & Title 2011).

2013-05-21T09:40:03 --> 2013-05-21T11:40:03
A small active region filament erupts, lifting up, dumping most of its mass toward one end.

An M5 flare from AR 1745 in the north triggers another smaller (C?) flare to the south of the equator.

2013-05-12T01:40:03 --> 2013-05-12T07:50:03
Loops in the AR on the west limb erupted, accompanied by some filament activity in the AR core.

2013-05-12T10:10:03 --> 2013-05-12T11:50:03
A puff like small eruption and a flare from the AR.

2013-05-12T09:10:03 --> 2013-05-12T10:30:03
A loop-shaped minor eruption from AR, resulting in some ribbon brightenings.

2013-05-12T20:10:03 --> 2013-05-12T21:50:03
A small scale eruption generated a coronal wave propagating toward the south above the east limb.

2013-05-12T00:00:03 --> 2013-05-13T00:00:03
Active region loops seen at 211 contract at a fairly fast speed over hours, mainly 11:00-17:00 UT. There are at least three sites of flux emergence nearby as seen in the HMI magnetograms. It is not clear if there are any physical connection between the loop contraction and flux emergence, possibly the latter causes reconfig in the corona and thus the contraction. Note there is no obvious flare or eruption occuring from this AR, so the contraction seems different from the flare-associated implosion ad Hugh Hudson proposed.

2013-05-11T03:10:03 --> 2013-05-12T00:00:03
Prominence material (304 channel, red) forms at the lower tip of funnel shaped coronal loops seen at 171 (yellow). Note there is a larger prominence (vertical column), likely in the foreground, blocks its view earlier; then this large prominence disrupts, leaving no prominence material in the neighborhood. Later funnel-shaped coronal loops "sag downward" and appear progressively brighter, leading to the formation of cool prominence mass at their lower tips. This is reminiscent of a similar but more pronounced event reported by Liu, Berger, Low (2012); http://adsabs.harvard.edu/abs/2012ApJ...745L..21L

A bundle of coronal loops (appears open field lines or streamer like) display wavy motions, possibly triggered by a nearby eruption, such as the filament eruption I just reported.

2013-05-11T20:00:03 --> 2013-05-12T01:20:03
Simultaneous filament eruptions to the south and north of the equator at symmetric positions. The southern eruption is more subtle than the obvious northern one I reported earlier today.
