QS filament eruption with post-eruption loop system.

2012-01-01T00:20:24 --> 2012-01-01T02:20:24

The eruption seems to be slow, although accompanying a weak two-ribbon flare (not showing up in GOES with a ~B4 background lebel). The associated CME is narrow, but it may reflect an edge-on perspective.

2011-12-31T16:00:04 --> 2011-12-31T16:59:28

This concludes the series of M-class flares from AR 11389, for which the standard cartoon model of eruptive flares does not seem to apply.

2011-12-31T12:50:24 --> 2011-12-31T13:40:12

This is the fourth example of confined M-class flares in AR 11389.

2011-12-31T20:20:24 --> 2011-12-31T22:50:24

The filament/prominence itself is best viewed at 304 A. It pushes material ahead of it, which is captured at 211 A and 171 A as a front (in emission). This eruption was associated with a slow CME that first appeared in the LASCO C2 image at 23:12 UT.

2011-12-31T20:10:24 --> 2011-12-31T22:10:24

The eruption originated from the northwestern periphery of AR 11386. No obvious pre-existing filament was seen.

2011-12-31T10:40:12 --> 2011-12-31T12:10:12

This is yet another event of coronal dimming due to an eruption, following three similar events. This one is the weakest, not accompanying flares.

2011-12-31T16:20:24 --> 2011-12-31T17:10:24

This may be a typical jet from an anemone region. But the base region does not seem to be as drastically reconfigured as in the cartoon model.

2011-12-30T20:00:04 --> 2011-12-30T21:30:04

This is the third in the series and the biggest one. The eruption is now associated with a C4.4 flare and responsible for a larger CME than the two previous ones.

2011-12-30T17:20:24 --> 2011-12-30T19:20:24

The eruption is best seen at 304 A. Images in other wavelengths show only part of the eruption without front-like structures ahead of the prominence as seen in some other events. The prominence appears to be linked to a region on the back side, although part of disk filaments show increased motions around the time of the eruption.

2011-12-30T14:30:01 --> 2011-12-30T15:59:25

The jet-like motion from the northern area seems to have triggered a flare in the southern area. In this case, the jet simply means motions in long, closed loops.

2011-12-30T10:10:12 --> 2011-12-30T12:30:12

The structure of the moving prominence, which seems to be anchored in the back side, reminds us of a flux rope. This motion is best captured in 304 A images with the 211 A and 171 A images reflecting only a limited range of the motion. TBD relation with a narrow CME first detected at 11:24 UT.

2011-12-30T09:00:04 --> 2011-12-30T09:40:04

This one seems to be isolated from other events. It is not yet clear it has to do with a narrow CME seen by LASCO at 09:48 UT.

2011-12-30T03:30:00 --> 2011-12-30T04:50:00

This is similar to the event around 29-Dec-2011 18:30. The corona above AR 11387 dimmed as a result of an eruption. But the details of the eruption may need further analysis.

Flares in AR 11389 seem to be hopelessly non eruptive....

2011-12-29T06:30:00 --> 2011-12-29T07:30:36

The jet in the southern hemisphere (to the west of AR 11386) leads to dimming in the region to the north across the equator. Shortly after this jet, one of those jets in AR 11384 (already reported) was seen, looking as if they were connected. This is reminiscent of simultaneous jets discovered by S. Freeland on Yohkoh SXT images.

2011-12-29T18:30:00 --> 2011-12-29T20:32:00

The corona above AR 11387 was seen to dim, although the AR itself did not seem globally dynamic. This pattern repeated at least three times during 29-31 December 2011. Only a marginal CME was recorded by LASCO.

On the western side of AR 11384, jets/surges were repeatedly observed. Were they related to the reconfiguration of the preceding spot including MMF?

2011-12-29T21:30:00 --> 2011-12-29T23:00:00

Another example of a big (M2.0) flare not associated with a CME. AR 11389 seems to be a CME-poor region. Regions like this may account for the statistics of ~50 of M-class flares being confined.

2011-12-29T15:30:00 --> 2011-12-29T16:59:24

The eruption is most vividly seen at 304 A with 211 A and 171 A images showing only a small part of it. The source region apears to be on the back side. Nothing like a CME front is recognized at 211 A.
