The southeastern part of AR 12473 hosted a filament that erupted. It did not give much impact on the overlying coronal structures.

Eruption or double sided flow, that is, toward west and higher and toward southeast and lower. AR 12473 has repeatedly shown this pattern.

This prominence disappeared after several hours of dynamic motions but did not leave signatures expected of an eruption. Observed only in 304 A images.

2016-01-01T22:20:23 --> 2016-01-02T02:20:23

This is the only major eruption from AR 12473 since the one on 29 December 2015 (which caused a G2 storm on NYE). Big dimming was seen over the limb. The flare showed downflows. It was preceded by a C2.7 flare, which may have played a role in loosening up the strapping field. The eruption included one that went southeast, reminiscent of the minor eruptions at earlier times. The eruption resulted in a bright CME with shock signatures and was associated with a minor (S1 level) SEP event.

2016-01-01T18:40:10 --> 2016-01-01T20:10:10

Similar pattern to the three earlier events (02 UT, 06 UT and 10 UT), but this one more clearly shows the presence of a dark filament, which was disturbed by the confined eruption in the southeast direction. In addition, the closed structure sticking out from the northwester part of the active region was seen to dim. These may have contributed to setting the stage for the big event a few hours later.

Similar pattern to the previous two events around 2 UT and 6 UT (minor eruptions to west and southeast). In this event, a flux rope-like eruption was added in the northwestern part of the region, although it still looked confined.

AR 12473 sometimes showed minor, confined eruptions to the west and southeast. This pattern was also seen in larger events from the same region, which was decaying into a simpler configuration.

After the big eruption that launched an Earth-directed CME, there were several surges in absorption in 304 A images, whose higher-temperature counterparts were also seen in 211 A and 171 A images. These originate from the western part of the leading spot of AR 12473. We need to examine magnetograms to find if they were due to moving magnetic features or flux emergence.

Sigmoid region AR 12473 finally erupted, resulting in a long-duration event that showed a high-temperature cusp structure above the post-eruptive arcade.

This flare from AR 12473 (https://twitter.com/halocme/status/679482830162931712) reveals eruptive signatures (coronal dimming, large-scale coronal propagating front, oscillations) even in intensity (non-difference) images.

The M1.6 flare in AR 12473 was eruptive with fast disturbances primarily to west/southwest. The prominence above the limb gives an impression that it is stuck at some height.

Mass injection from the western leg of the filament caused brightening at the other leg. The region between them also showed minor brightening, presumably reflecting reconnection due to a slight ascent of the whole structure.
