2012-12-23T20:56:35 --> 2012-12-23T21:56:35

An off-limb eruption (SE) initiating from behind the disk generates thin bright emission patterns as the eruption takes off.

2012-12-23T19:08:35 --> 2012-12-23T23:48:35

An eruption occurs in the northern reaches of a N-hemisphere AR. There is no obvious filament in 211/193/171, but a clear post-eruption arcade. The perturbed field couples into QS field NE-ward of the region, and apparently even well eastward of that.

2012-12-21T05:28:03 --> 2012-12-21T10:52:03

A large pretty filament eruption at the S limb. The Sun clearly does not know much of the Maya calendar so the eruption is not directed earthwards.

2012-12-21T06:00:03 --> 2012-12-21T06:56:03

This minor eruption is otherwise unremarkable, except that this is the only phenomena the Sun has produced at least close to the disk center in the so-called end of the world day. So this is about as close to the catastrophe as we will ever get. Sorry, guys.

2012-12-20T20:33:03 --> 2012-12-21T00:00:03

A very nice coronal wave behind the W limb. In 211A it nicely highlights the connectivity of the field. This wave is even vaguely present in 304A

2012-12-20T01:00:03 --> 2012-12-20T05:39:03

Faint filament eruption on the NE limb. There is a contemporary darkening in the loops of the AR right to the S of the highlighted region.

2012-12-10T10:00:03 --> 2012-12-10T19:00:03

Two filament eruptions occurring on the southeast limb within 2 hours or each other; some would suggest that these are somehow causally related

2012-12-09T15:00:03 --> 2012-12-09T20:00:03

Another eruption of a tiny filament, though appears to be slightly larger than the related event several hours earlier: http://lmsal.com/hek/her?cmd=view-voevent&ivorn=ivo://helio-informatics.org/ER211_MarcDeRosa_20121216_192800

An eruption of a tiny filament? located wtihin a small active region AR 11626

2012-12-12T19:25:03 --> 2012-12-13T10:00:03

A QS filament (connecting to a small near-equatorial AR) erupts. There is a dark cusp-like shape on the eastern leading edge of the coronal reconfiguration. Some 11h after the initial eruption started, a second occurs, now at the eastern end of the original eruption.

2012-12-11T14:00:03 --> 2012-12-11T17:32:03

A repeatedly activation QS filament in the NE erupts simultaneously with a relatively compact decayed AR in the S hemisphere.

2012-12-11T00:00:03 --> 2012-12-12T00:00:03

Within the 24h period of 2012/12/11, at least five activations are seen involving the leading end of a filament/prominence configuration in the NE. The leading segment of the filament brightens, and then reveals an EUV extension arching high above the trailing end of the configuration, which is clearly affected (with oscillatory components) by the repeated activation.

2012-12-09T16:14:03 --> 2012-12-09T18:52:03

A small filament on the eastern limb, trailing an active region can be seen to erupt, spinning as it lifts off and then most of the material appears to follow a field line across the limb to the far side and come back down as coronal rain. The field lines in 171 in the leading active region appear to change a little just before the eruption, particularly in the lower right corner of the video.

2012-09-12T04:00:03 --> 2012-09-12T05:59:27

This period is isolated because of repeated jet activity in the region right on the west limb. The individual jets are not associated with DH type III bursts in this case.

2012-12-07T21:00:03 --> 2012-12-07T22:30:03

The connection between this third eruption (from either AR 11623 or AR 11625) with the preceding two seems more tenuous than the connection between the first and second events.

2012-12-07T11:00:03 --> 2012-12-07T17:30:03

The second of three eruptions from the west limb. This eruption is from a quiescent filament lifting off. The magnetic structure associated with this filament (which also had a cavity above) may have been destabilized by the first eruption.

2012-12-07T08:30:03 --> 2012-12-07T10:16:03

The first of three eruptions from the west limb. The first one originates from either AR 11623 or AR 11625.

2012-12-07T05:22:03 --> 2012-12-07T07:00:03

A faint bubble with relatively low emission is seen to rise through the corona. There are no clear signs of chromospheric/photospheric evoluation causing this small eruption.

2012-12-07T05:00:03 --> 2012-12-07T07:00:03

Although most of the filament material seems to drain back down to lower heights, some do seem to escape via open field lines.
