This event may be a confined (failed) eruption but there is at least some dimming high in the corona.

2012-12-26T00:10:11 --> 2013-01-03T21:10:11

This cavity should be located at very high latitudes since it (and the associated prominence) does not seem to move substantially with solar rotation over the 9-day period or at least for the last 7 days.

2013-01-03T19:10:11 --> 2013-01-03T21:10:11

The small filament eruption results in a two-ribbon flares and dimming at high altitudes.

2013-01-03T04:20:23 --> 2013-01-03T05:50:23

The eruption associated with this small dimming occurs in a region just on the limb on the basis of how the post-eruption arcade looks like.

2013-01-03T01:10:11 --> 2013-01-03T02:10:11

This may at first look like another backside event. However, a small eruption is found on the visible side to precede the dimming at high altitudes.

2013-01-03T09:00:03 --> 2013-01-03T10:30:03

Material is injected from the southern leg, apparently moving the northern leg of a cus-like loop system.

2013-01-02T17:00:03 --> 2013-01-02T18:20:03

The filament material largely falls back as seen in 304 A images, but the higher corona seems to be partly opened up by the eruption. The associated CME is marginal.

2013-01-02T06:00:03 --> 2013-01-02T08:00:03

Perhaps the prominence started to be activated a little earlier, but the movie captures its rotating motions projected on the plane of the sky. The corona at higher altitudes slightly dimmed as the prominence gets accelerated.

2013-01-01T01:45:35 --> 2013-01-01T03:05:35

Another jet from a high-latitude region in the northern hemisphere. The region appears to be just on the limb.

This annotator (halocme) happens to be assigned for a generally CME-quiet period, but LASCO data sometimes show CMEs. For example, refer to the C2 difference image 01:25-00:48, which marks an unimpressive but broad CME from NE, making me wonder what its origin is. This AIA movie may show a marginal indication of the eruption between 00:24 and 00:46 to maybe wishful eyes. From STB, the source region is N20E15, meaning it is 56 degrees behind the east limb from Earth view.

2012-12-31T16:00:04 --> 2012-12-31T18:30:04

Although much of the erupted material seems to fall back, the erution makes it into the interplanetary space as a minor CME. The eruption is associated with a B-class flare not registered in the NOAA flare list.

2012-12-31T02:50:23 --> 2012-12-31T04:31:11

The origin seems to be a region 5-10 degrees behind the limb. The propagation is preferentially northward. Alas, the cadence of EUVI on STB is reduced to 10 minutes.

2012-12-30T19:00:03 --> 2012-12-30T21:00:03

Although the source region appears to be not deeply occulted, the eruption is not spectacular in these images. The associated CME is also marginal.

2012-12-30T05:45:35 --> 2012-12-30T06:45:35

The eruption originates in a quiescent region around E90 (STB information), and it is associated with a narrow but bright CME. Patches of the prominence material are seen to brighten as it erupts.

2012-12-30T01:00:03 --> 2012-12-30T02:30:03

Another jet from the north pole, accompanying dynamic motions at the footpoint.

2012-12-29T23:20:23 --> 2012-12-30T01:31:11

The eruption contains untwisting motions. The front is seen to form ahead of the prominence eruption. How does the linear structure in the prominence develop?

2012-12-29T22:50:23 --> 2012-12-30T00:10:23

It appears that the outward motion passes the edge of the AIA FOV, but there is hardly an associated CME. The source region should be on the far side, but even with STB data it is hard to identify the region.

2012-12-29T14:15:35 --> 2012-12-29T15:25:35

The jet is very diffuse, but associated with dark material ejected from the footpoint and falling back.

2012-12-29T09:30:35 --> 2012-12-29T10:30:35

The foot-point brightening is clearly observed in association with the jet.

2012-12-29T04:15:35 --> 2012-12-29T05:59:35

Very diffuse, but AIA can still observe it.
