2012-03-05T21:40:12 --> 2012-03-05T22:40:12

This jet seems to start around the end of a filament (or loop) as it goes down. But their relation is not clear.

2012-03-05T18:00:05 --> 2012-03-05T20:00:05

This movie contains three flares (one C-class and two M-class), but none of them is eruptive although they show motions along closed loops.

2012-03-05T09:30:00 --> 2012-03-05T12:00:00

The eruption of the filament material is well traced in the three channels, but the 211 A images do not clearly show a front. The associated CME is narrow and not spectacular.

2012-03-05T01:40:00 --> 2012-03-05T06:00:24

This event appears to consist of two stages. First, a relatively minor eruption is seen. Then another eruption comes from the core of the active region making a major CME. Consistent with a leading scenario of CME initiation? Both eruptions accompany global waves, first seen only over the limb, and then also on the disk with the second eruption.

2012-03-04T19:00:04 --> 2012-03-04T22:00:04

The LASCO C2 difference image of 21:24-20:36 shows a bright CME with irregular shape on the NE limb, but the next frames are left with an unimpressive outflow which may not qualify as a CME. This movie again shows that only the 211 A channel (out of the 304-211-171 combination) indicates large-scale eruptions, possibly corresponding to the CME.

2012-03-04T02:00:04 --> 2012-03-04T09:00:04

LASCO data show gradual formation of a CME between 5 UT and 6 UT. It is not straightforward to determine where the front is. In this movie, only the 211 A images suggest the CME onset. The source region may be far behind the limb.

2012-03-04T17:10:13 --> 2012-03-04T18:19:49

Associated with a C3.2 flare, this does not seem to be a full-blown eruption. Indeed no CME is associated.

2012-03-04T10:00:05 --> 2012-03-04T12:00:05

A clear EUV wave even in intensity images. But full-disk running difference images show propagating disturbances both over the limb and on disk. This event was a partial halo CME. The movie shown here nicely captures post-eruption high-temperature regions including current sheets.

2012-03-04T02:45:00 --> 2012-03-04T03:46:12

No flare obviously associated with this eruption. It is too minor to lead to a CME.

2012-03-03T17:00:04 --> 2012-03-04T05:00:04

Eruption and small flare just inside the NE limb, with a very unusual (and pretty) set of post-event loops: sharply-cusped loops towards the N and a strongly-inclinded glowing arcade towards the S (over a region where a smallish eruption seems to have started the sequence).

2012-03-02T06:36:04 --> 2012-03-03T00:00:04

Flare in an AR just over the NE limb. Loop systems are seen to reconfigure for hours prior to the flare, and post-eruption loop system shows subsequent continued evolution. A helmet over a pair of arcade-like configurations suggest the presence of a null point above the flaring region.

2012-03-01T14:44:04 --> 2012-03-01T16:44:04

Apparent reconfiguration of a filament structure in QS connected to a small AR. The activation shows multiple regions of moss, successively lighting up as matter appears to flow from AR towards the NE along the filament, highlighting connections to surface.

2012-03-01T08:04:04 --> 2012-03-01T13:32:04

QS eruption, from a mid-sized AR arching around over a PIL in QS. The eruption shows a weak wedge towards is E end.

A growing dipole produces a small eruption, follwed by coronal dimming and beautiful front of post-flare brightening.

2012-02-19T13:58:04 --> 2012-02-19T20:14:04

A beautiful filament eruption on the limb. In the initial phase of the rise an unswirling "slinkie" could be seen, and later it appears as a spinning cone. Part of the filament is seen to fall back down while most of it eripts. It is a little unusual that the emission ends abruptly in the middle of the filament, as it only half of it was emitting. As if the 304A slinkie is only attached to the surface at one end and the other end is free.

A few vertical bundles of coronal loops are distributed at visually even intervals over a straight line. Each of them, conceivably, is footed at a small unipolar region; but there are more unipolar regions around, why only these are emitting at this wavelength? One could also track these bundles since their appearance. Due to the angle of view and lack of background features, these bundles might be particularly interesting to study.

2012-02-24T03:00:04 --> 2012-02-25T04:00:04

Similar to the larger event earlier in the day, this filament eruption shows no GOES X-ray signature in spite of the large two-ribbon "flare" front that follows the filamant eruption. There is a marked rise in proton flux starting at ~3 UT on the 25th. Was this event or the earlier event responsible?

A large rapid filament eruption is followed by a huge two-ribbon "flare" front moving across the disk. The GOES X-ray signature of this event is unusally faint.
