2014-12-23T10:50:23 --> 2014-12-23T11:30:23
This is an eruption probably from behind the limb. Coronal dimming is seen, but it is a failed eruption. Interestingly the loops around and over the dimming region are seen to oscillate, which may be related with confinement.

2014-12-23T06:30:35 --> 2014-12-23T08:46:35
The C1.8 flare in AR 12241 looks dynamic, but it probably belongs to a confined eruption, and the filament that traces the main flare emission does not seem to erupt. Although the relationship is TBD, this flare was preceded by another C1.5 flare in AR 12242 (to southwest) and small prominence eruption on the southwest limb.

Filament eruption, with much of the filament confined to a higher new configuration. Looks like an aneurism from the initial filament configuration, that at least partly remains lying low.

2014-12-21T10:30:35 --> 2014-12-21T13:30:35
This is the last one in the series that left in-situ signatures at 1 AU even though the eruptive signatures in the low corona were not very outstanding. The M1.0 flare started in AR 12241. There was nearly a simultaneous eruption from AR 12244 (near the left edge of the movie). As in the previous examples, the main eruption with separating ribbons rooted by post-flare loops (in the encircled area) disturbed the neighboring south-to-southwest areas, including flaring in AR 12242.

2014-12-20T00:00:03 --> 2014-12-20T01:30:03
This X1.8 flare was from AR 12242. Again, the eruption was noticed most clearly in the core region in the form of separating ribbons, between which bright post-flare loops formed. Without clear wave signatures, the southern areas were clearly affected, showing ribbon emission. After the CME was launched, the opening up of the loops seemed to cause a secondary eruption from the southern areas.

2014-12-18T21:00:35 --> 2014-12-18T23:30:35
This flare seems to be associated with a halo CME in LASCO C3 data on Dec 19, which is a natural candidate for the cause of the second IP signatures on Dec 21. The encircled area looks like a classical two-ribbon flare, but the eruption also affected a large area to the south. Interestingly, there was a filament eruption near the southeast limb just before this flare, but their possible connection is TBD. Without LASCO C2 data (still unavailable as of 24-Dec-2014 17 UT), it is hard to understand how this event is mapped into a halo CME.

This is the first of four events that did not look very eruptive when images were looked at casually but that nevertheless produced disturbances at 1 AU. In this flare the key to understanding this puzzle may be the extension of two-ribbon emissions.

2014-12-22T11:30:03 --> 2014-12-22T22:00:03
A minor prominence near the north pole gradually lifts off, disappears, not quite an eruption though.

An eruption near SW limb, causing two-ribbon brightenings.

2014-12-21T00:00:03 --> 2014-12-21T03:50:03
A small active region filament near NE limb erupted first, followed by another larger filament, most likely from behind the limb.

2014-12-21T10:00:03 --> 2014-12-22T00:00:03
A prominence on NE limb was activated, material being lifted off and dumped nearby. Note in the late phase, ~20 UT, a cusp geometry, possibly indicating magnetic reconnection at a Y-type null point, which allows cool prominence material being transported in different directions.
