2013-01-18T17:50:23 --> 2013-01-18T18:30:23

The small eruption, which assumes counter-clockwise motions, appears to drive a jet, most readily seen at 211 A.

2013-01-18T15:30:35 --> 2013-01-18T16:20:35

This is not quite a filament eruption, but it may represent processes that make the filament unstable.

2013-01-18T06:15:35 --> 2013-01-18T07:59:35

Energy is injected into the southern leg of large-scale trans-equatorial loops, and propagated into the northern leg. Then changes in the top part are observed, especially in difference images. The sowthward propagating brightening on disk may or may not be related.

2013-01-18T09:15:35 --> 2013-01-18T10:15:35

This is the third time AIA observed the phenomenon like this within a 10-hour period. An injection of material into large-scale closed loops from the southern leg makes the northern leg visible slightly later.

2013-01-18T04:30:35 --> 2013-01-18T05:19:47

Similar to the previous event. Aninjection of material into large-scale closed loops from the southern leg makes the noethern leg visible slightly later.

2013-01-18T01:20:23 --> 2013-01-18T02:31:11

This may appear as an ejection, but it is actually an injection of material into large-scale closed loops. The northern leg becomes visible (only in difference images) after the injection.

2013-01-17T20:50:23 --> 2013-01-17T22:20:23

The eruption starts from a prominence seen at 304 A and appears in 171 A and 211 A as a closed structure. The large filament to the west of the eruption is not affected.

2013-01-17T08:20:23 --> 2013-01-17T09:30:23

The ejection is resolved by AIA, traced to slightly displaced footpoints. The phenomenon seems to be recurrent.

2013-01-17T05:45:35 --> 2013-01-17T06:55:35

Two episodes of narrow ejections. Their relation needs to be investigated.

2013-01-17T04:20:23 --> 2013-01-17T05:40:23

This seems to be a minor eruption. The lack of post-flare loops suggest that the source region is behind the limb or that magnetic reconnection does not play a role in the eruption.

2013-01-16T21:00:35 --> 2013-01-16T23:00:35

There appear to be at least three jets in the encircled area; two in the direction of 1 o'clock and another in the direction of 11 o'clock. One of the former follows a mini-filament eruption but there may be no relation between them.

2013-01-18T16:50:23 --> 2013-01-18T17:59:59

It appears that the propagation is mostly southward with the northen part probably representing the CME.

2013-01-18T16:00:04 --> 2013-01-18T19:00:04

There were two C-class flares (16:50 C5.8 and 17:41 C2.3). In both of them, two regions far apart brightened nearly simultaneously. There was a type II radio burst associated with the first flare. It was probably from the eastern compact flare (encircled) because of its association with an EUV wave. The flare in the western region was also eruptive but it was more local.

2013-01-17T02:10:11 --> 2013-01-17T03:40:11

A surge-like outflow in the southern hemisphere, seen in absorption at 211 A, appears to trigger trans-equatorial loops to oscillate.

2013-01-16T19:30:35 --> 2013-01-16T22:00:35

The prominence is seen to split and to fall down. The downward motion seems to be guided by closed structures seen in 171 A, but not as clearly in 211 A.

2013-01-16T19:18:10 --> 2013-01-16T21:00:10

We see some downward motions typical of eruptive events. We missed the eruption itself because of the SDO satellite maneuver called EVE Cruciform. The first decent image was from 19:18 UT, while the X-ray started to increase at 18:21 UT (the peak flux was C2.2 at 19:23 UT). It would have been nice to observe the eruption itself rather than the aftermath of a partial halo CME.

2012-07-19T04:00:04 --> 2012-07-19T07:00:04

Although the wave signatures early in the event and close to the flare are not clear, the propagation of the disturbances are noticeable over the limb. Need 3-d analysis to understand the relation between the front, flux rope and CME.

2013-01-16T09:30:35 --> 2013-01-16T11:30:35

Following the activation phase, the prominence/filament finally erupted, but apprently not with too much success, on the basis of little changes in the corona in 211 A images (green).

2013-01-16T02:00:03 --> 2013-01-16T09:30:03

Toward the end of this phase, the main body of the filament appears to split into thin threads. Can brightenings lower down (perhaps reflecting flux emergence or cancellation) tell us what is going on?

2013-01-16T06:50:23 --> 2013-01-16T07:50:23

Around the same time a disk region (top right) had a minor eruption, another region on the east limb (encircled) also erupted.
