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.

2014-11-02T20:00:03 --> 2014-11-02T22:20:03
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.

2014-11-02T19:30:35 --> 2014-11-02T21:40:35
The region was still behind the limb This was pronounced in a radial eruption rather than in lateral expansion, which often explains a LCPF.

2014-11-03T03:30:35 --> 2014-11-03T04:40:35
This is similar to the previous event at Nov 2, 16:50. A C4.2 flare occurred in AR 12201, which was associated with a minor eruption and large-scale coronal propagating front (LCPF).

2014-11-02T16:40:11 --> 2014-11-02T17:30:11
The eruption looks like a jet or surge to northwest, but we see a large-scale coronal propagating front (LCPF) to other directions, especially to northeast.

The first ejection of prominence material did not go through, but the second one seems to have opened up large-scale structures.

The region (AR 12205) was still 20 degrees behind the limb, but this was a bigger eruption than the previous one around 02 UT. We clearly see loop oscillations and reflection of coronal wave (large-scale coronal propagating front, LCPF) as it was launched by the eruption. Difference movies show that the easst limb of the direction of 8 o'clock to 1 o'clock was traversed by the LCPF.

As is often the case, the front is first seen in coronal lines. Part of the prominence is seen disturbed, but the source region is still about 20 degrees behind the limb.

Flare, eruption, and coronal wave from a region in the NE quandrant, persisting in similar activity for the past three days.
