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.

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.

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.

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.

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.

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.

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.

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?

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.

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.

This flare may cloud an attempt to explain all flares in terms of the so-called standard 2d reconnection model.

The wave propagates mostly to north, and appears to be trapped by other active regions across the equator. The associated flare was C5.4.

This region, AR 11387, has produced EUV waves around the times of M4.0 (25-Dec-2011 18:11), C7.7 (25-Dec-2011 20:23), and M1.5 (26-Dec-2011 02:13) flares. Now the flare magnitude is M2.3 (double peaked), but the eruptive behavior does not quite reach out.

This wave accompanied the CME that looked quite similar to the one associated with the M4.0 flare about 8 hours before. The flares in AR 11387 associated with EUV waves were of short duration.

This may be called a wave by some. Indeed, at 171 A, fast recurrent pulses are clearly seen, which probably represent waves. However, is the propagation front really a wave as an EIT equivalent would have been labeled?

Another EUV wave from AR 11387. Reflecting the magnitude of the associated flare (C7.7), this wave was not as spectacular as the previous one associated with a M4.0 flare. The propagation was centered in the north to east queadrant.

This wave accompanied a bright CME, which does not seem to be very fast. The associated flare was quite impulsive and was M4.0.

AR filament eruption, with wave-like coronal perturbation, a spray/surge-like movement of chromospheric material, and coronal oscillations.
