2016-02-14T15:30:34 --> 2016-02-14T19:00:34

The eruption occurred in a quiescent region, and the flare brightening was almost negligible. No CME.

2016-02-14T19:10:10 --> 2016-02-14T20:00:10

Another flare in AR 12497. We need difference images to bring up the eruption, which starts dramatic but does not go to the interplanetary space - no CME.

Another flare in AR 12497. The minor eruption to west and south can be seen only in difference images.

2016-02-13T15:10:10 --> 2016-02-13T16:00:10

In difference images, there are signs of eruption in this flare at AR 12497 , but not clearly or globally seen, not comparable to the C8.9 flare on 11 Feb 2016. No CME.

2016-02-15T15:50:06 --> 2016-02-16T00:00:06

A small eruption from a weak active region (AR 12499).

2016-02-14T03:10:10 --> 2016-02-14T03:50:10

Nearly the same pattern as the previous event (13 February 2016, 22 UT).

2016-02-15T14:00:06 --> 2016-02-15T19:00:06

Coronal jets in AR 12497, which leads to a synchronous filament activity near the west limb.

2016-02-13T22:00:06 --> 2016-02-13T22:36:06

A minor eruption affected the large-scale loops that encompassed two bipolar systems. The coronal rain survived the eruption.

2016-02-15T00:00:06 --> 2016-02-16T00:00:06

Multiple small-scale coronal rains observed near the east limb.

2016-02-13T20:40:10 --> 2016-02-13T21:20:10

A minor eruption/C2.5 flare occurred in AR 12497 (around 12497). Running difference images may give an impression that fast ejecta from it moved to east, hitting another region close to the east limb and causing it to erupt. But this can be just by coincidence,

2016-02-15T04:50:06 --> 2016-02-15T14:00:06

Long range filament material transfer probably over large-scale coronal loops.

This is likely to be the first decent coronal wave in 2016 (another manifestation of decreasing solar activity). In addition to the propagation to south, the disturbances were also directed to northwest, passing the limb. This probably tracked the nascent CME.

2016-02-11T20:05:22 --> 2016-02-11T21:31:22

The eruption occurred in AR 12497, associated with a long-duration C8.9 flare. No clear cool filament was seen, but from the way the flare ribbon and post-eruption arcade formed, a somewhat curved polarity inversion line was involved. Coronal dimming was not very extensive, but a partial halo CME was observed by LASCO.

Material is seen to fall in two closed systems, which may both be part of the same restructuring or opening. We fail to see a CME clearly associated with these downward motions.

2016-02-12T10:30:34 --> 2016-02-12T11:30:34

This M1.0 flare occuured in AR 12497. It showed some eruptive signatures, but the effect was much more localized than the C8.9 flare that had occurred in the same AR on the previous day. For example, no clear persistent dimming, consistent with the absence of an associated CME. The observed loop oscillations may be triggered by fast-mode MHD waves, indicating that these waves can be launched without a CME.
