Coronal wave associated with a minor eruption and C4.8 flare (Coronal Wave)

Detected by halocme, Submitted at 2016-05-16T17:17:41

2016-05-14T15:10:10 --> 2016-05-14T16:10:10

This is the third large-scale coronal propagating front (LCPF) associated with a C-class flare in AR 12543 within a six-hour period. It is similar to the previous one, including another region to northwest that shows wave-like variations.

Coronal wave associated with a minor eruption and C7.4 flare (Coronal Wave)

Detected by halocme, Submitted at 2016-05-16T17:03:57

2016-05-14T11:15:34 --> 2016-05-14T12:15:34

This large-scale coronal propagating front (LCPF) is a stronger version of the previous one around 09:30 also from AR 12543. In 171 A images, another region to the northwest also shows wave like variations.

2016-05-14T09:15:34 --> 2016-05-14T10:31:34

Immediately following the large-scale coronal propagating front (LCPF, coronal wave) from AR 12543, a flaring/eruption was seen in a distant region AR 12544, east of the central meridian. Since the wave propagation was preferentially toward south to west, perhaps the occurrence of the latter event was by coincidence, rather than induced by the LCPF.

Coronal wave associated with a minor eruption and C2.5 flare (Coronal Wave)

Detected by halocme, Submitted at 2016-05-16T16:34:17

2016-05-14T09:15:34 --> 2016-05-14T10:15:34

This large-scale coronal propagating front (LCPF) seems to have been launched by a small eruption that was also associated with a C2.5 flare in AR 12543. The propagation was mostly south to west.

Eruptive motions in AR 12543 (Eruption)

Detected by halocme, Submitted at 2016-05-16T16:14:46

2016-05-14T06:10:10 --> 2016-05-14T07:10:10

Eruptive motions started locally associated with a compact brightening. The motions largely traced closed loop structures.

Minor prominence eruption (Filament Eruption)

Detected by halocme, Submitted at 2016-05-16T15:59:41

2016-05-14T06:00:06 --> 2016-05-14T07:00:06

The eruption was minor, not showing footpoint brightening - this may be partly because the source region might have been occulted. But the prominence was clearly located below the cavity (flux rope), pushing it upward.

Filament Eruption (Filament Eruption)

Detected by jinmeng, Submitted at 2016-05-14T01:20:29

2016-05-13T07:00:06 --> 2016-05-13T18:00:06

Filament eruption near the west limb.

Filament Eruption (Filament Eruption)

Detected by jinmeng, Submitted at 2016-05-14T01:20:29

2016-05-12T14:20:06 --> 2016-05-13T02:50:06

A filament eruption near the west limb is observed. The eruption disturbed another small filament to the south and lead to another eruption at last.

Filament Formation and Eruption (Filament Eruption)

Detected by jinmeng, Submitted at 2016-05-14T01:20:29

2016-05-13T06:20:06 --> 2016-05-13T20:20:06

A filament formation and eruption process is observed. The final eruption occurred right after an activity in the nearby active region.

Sympathetic Filament Eruption (Filament Eruption)

Detected by jinmeng, Submitted at 2016-05-12T18:11:42

2016-05-11T00:00:06 --> 2016-05-11T13:50:06

Filament in the north of the FOV erupted first. The eruption seems to cause another filament (in the south of the FOV) start to oscillate as well as some reconnections around it. The second filament enventually erupted.
