2014-11-22T12:50:23 --> 2014-11-22T19:50:23
The C2.1 flare in AR 12209 accompanied a confined filament eruption. This appears to be connected with the activation (and partial eruption?) of the filament southwest of the active region.

2014-11-22T05:55:12 --> 2014-11-22T06:25:12
The flare was again triggered in the trailing part of the active region and the confined ejections were produced in the west and southwest directions.

Two small eruptions across the equator that are seen around the same time.

2014-11-20T19:30:00 --> 2014-11-20T22:09:36
The biggest active region since 1990, AR 12192, returned as AR 12209 about 1/3 of the original size. Major flares in this region were notoriously non-eruptive, and it has not even produced M-class flares since Nov 17. This one is only C2.5. It started in the trailing part of the AR with an ejection, which looked like trapped by large-scale magnetic field within the region.

This probably represents a narrow ejection near a region of open/closed field boundary. The helical structure is hard to see.

2014-11-04T07:50:23 --> 2014-11-04T10:00:23
Two M-class (M2.6 and M2.3) flares occurred in succession in AR 12205. The second one was more eruptive. It accounted for lateral motions of large-scale structures over the limb, probably in the form of a coronal wave (LCPF) which is not clearly seen even in difference movies.

AR 12205 seemed to be right on the limb, and the flare magnitude was M6.5. Like the previous event around 11:20 UT (M2.2 flare), a coronal wave (LCPF) and loop oscillation are clerly seen. But the propagation of the LCPF into the disk is insignificant.

The source region should be slightly behind the limb since there is no foot-point brightening. Untwisting is more readily seen after the prominence reaches a certain height.

This appears to have triggered at the southern leg of a loop structure. No filament was seen in 304 A.

Several small eruptions are seen. None of them seem to have opened up the overlying corona.

As AR 12205 approached the east limb, the flare associated with an eruption became stronger. This one was M2.2 flare. Difference movies show a LCPF propagating clockwise beyond north pole, but loop oscillations were also seen south of the flare.

The region was still behind the limb This was pronounced in a radial eruption rather than in lateral expansion, which often explains a LCPF.
