This seems to be a long-lasting structure. It is not clear whether the more smooth western part is connected with the eastern part, in which the outward motions are more easily seen.

2013-09-13T00:00:03 --> 2013-09-13T05:00:03

This is seen only in 171 A images above the prominences in 304 A images. There is no CME in this range of position angle.

2013-09-11T18:50:23 --> 2013-09-11T20:00:23

A minor jet and associated eruption may be associated with flux emergence that is marginally captured here.

2013-09-11T12:20:23 --> 2013-09-11T13:50:23

In difference images, the changes are seen only at high altitudes within the AIA field of view. The apparent dimming seems to be cause by lateral motions of large-scale loops. This can signify an eruption or a wave.

2013-09-11T02:30:35 --> 2013-09-11T03:30:35

The eruption involves motions that look like counter-clockwise. Loops to the north are affected by the eruption, leaving temporary dimming notably in 193 A images. No CME is observed by LASCO.

2013-09-11T00:00:03 --> 2013-09-11T01:20:03

Looking at part of the areas in the movie, it is possible to be struck as jets. But it appears that a lot of things are going on, such as rising and then horizontal motions of loops in the western part, eruption of a low-lying prominence, opening up of higher structures in the eastern part, etc. No associated CMEs in LASCO data.

2013-09-12T21:30:35 --> 2013-09-12T22:30:35

Footpoint brightening suggests that this jet originated on the visible side.

2013-09-12T21:30:35 --> 2013-09-12T23:30:35

This eruption is very diffuse and best captured in 171 A images. In positive images it is hard to recognize it. This event may have to do with a larger eruption involving loops to the east with prominences in the same line of sight.

2013-09-12T17:30:35 --> 2013-09-12T21:00:35

Although the eruption itself is not clearly captured, there is one because of a two-ribbon brightening. Loops extending over the limb show slight lateral motions, probably signifying that higher structures erupted and observed as a minor CME.

2013-09-12T10:50:23 --> 2013-09-12T14:00:23

A minor eruption likely from backside. Its CME association is marginal.

Another flaring in AR 11839. The background-subtracted peak flux is something like A3. The creation of hot plasma is also seen in the western region (not numbered).

The peak GOES 1-8 A flux is B1.8, but it is less than B1.0 if background is subtracted. It is interesting to note that the first brightening is seen in AR 11839 (middle), followed by others in the eastern and western regions (without AR numbers).

2013-09-12T10:40:12 --> 2013-09-12T12:00:36

This is a major flare of the day. The peak GOES 1-8 A flux is at B2.6, increased from the A9 level. But it is not included in the GOES flare list. Hot plasma is seen to be created in a couple of locations in AR 11841.

2013-09-12T02:45:00 --> 2013-09-12T03:25:48

This brightening (causing the GOES 1-8 A channel to increase from B1.2 to B2.0) is in association with turbulent motions in the loop system in the southern extension of AR 11839. The movie at least indicates the generation of 6 MK plasma.

2013-09-13T14:00:03 --> 2013-09-13T21:00:03

The slow ascent of the prominence had started before 14 UT. It is hard to link this eruption with the filaments lying on the visible disk. The associated CME, which was first found around 19 UT in LASCO C2 data, was quite major in the sense that it was still visible at the southern or souteastern limit of C3 data.

2013-09-12T17:30:35 --> 2013-09-12T19:00:35

This appears in depression in 211 A and 193 A images. The western footpoint brightens nearly simultaneously with the outflow.

2013-09-12T17:00:03 --> 2013-09-13T00:00:03

The outward motion (in 304 A) to northwast between 22:30 and 23:30 UT is reminiscent of the quasi-periodic fast propagating wave usually seen in 171 A images (Wei Liu et al. ApJL, 736, L13, 2011). This is long after the associated CME takes off (some time between 18 UT and 19 UT as seen in 211 A over the limb). The white-light appearance of the CME is somewhat complex, not going through gradual to sudden acceleration.

2013-09-11T12:00:03 --> 2013-09-11T21:42:03

LASCO C2 data show a flux-rope-like feature around 17 UT with closed loops ahead. The CME becomes obvious only around 21 UT. Although it is possible that this is a deeply occulted event, the hesitant motions of the prominence may represent the low coronal manifestations of the CME, which is more clearly seen to form at higher altitudes.

2013-09-11T08:00:03 --> 2013-09-11T10:00:03

The untwisting is more readily seen in the southern leg. There is clear connection of the northern leg with the filement (channel) on the visible side. The eruption drives a decent CME that is first seen by LASCO C2 at 09:24 UT and traceable to the edge og C3 (around 19 UT).

2013-09-04T20:00:03 --> 2013-09-05T00:00:03

Filament from an off-limb active region shows a lot of dynamics involving both colder filament material and warmer coronal loop structures.
