This flare, in AR 12732, showed eruptive signatures such as outward motions and cusp-like post-flare loops. But the large-scale effects were limited. The active region was already tired.

2019-01-03T16:20:25 --> 2019-01-03T18:40:25
The region was ~5 degrees behind the limb, which arrived in Earth view only as a plage region. The eruptive motion was largely toward north, hardly contributing to a CME.

This eruption is from an isolated sigmoid in the quiescent region, causing temporary dimming in the adjacent region.

This is best seen in intensity images in 304 A. Other low coronal signatures seem to be quite limited, implying that it is not a major event. The associated CME is not impressive (http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20190102.234807.w012.v0596.p251&frame=6&r_. Part of the reason may be that equatorial coronal holes prevent the eruption extending toward the equator. This event was predicted by a famous solar physicist shortly before the occurrence (https://twitter.com/cosmic_jet/status/1080578605271273472).

The B2.8 flare in AR 12732 was quite eruptive, showing an EUV wave propagating mostly northward with counterclockwise rotation.

The outward motion included right-handed rotation.

The northwestern quadrant of the Sun saw at least three minor eruptions that started within 1.5 minutes apart.

It is not clear whether this represents a mass ejection, but the origin and development of the concave structure seems to be a mystery. The phenomenon is specific to the 171 A channel. A better view may be obtained by PROBA-2/SWAP (174 A) and GOES/SUVI (171 A) with larger fields of view.

2018-12-31T22:00:09 --> 2019-01-01T00:00:09
This is extremely hard to see in intensity images, but a quite large volume of the corona is seen to move out. The eruptive prominence around the northern leg may contribute the whole eruption.

2018-12-31T19:00:09 --> 2018-12-31T20:30:09
During the growing phase of AR 12732, an eruption occurred in the eastern bipole, which appeared to trigger another in the western bipole. These eruptions ignited a weak wave propagating northward beyond the active region.

This jet may have been aligned with local open field lines that were bending toward the equator.

Just one of those jets. An ejection of the chromospheric material may be traced to a relatively large distance.

2018-12-24T05:50:25 --> 2018-12-24T07:10:25
An eruption from a compact region ~40 degrees behind the east limb. The region decayed before it rotated on to the visible side, but it was probably spotless even at the time of the eruption.

Repeat of the slow and large-scale eruption seen in 171 A images. These events have no presence in LASCO data.

2018-12-29T00:00:09 --> 2018-12-29T07:00:09
A slow and large-scale eruption primarily detected in 171 A images. This phenomenon seems to be more often seen during a solar minimum. This one seems to be related with prominence activity at the legs of the eruptive strcuture.

The low-temperature component traces the helical structure of the magnetic field involved in the ejection.

This is so diffuse that difference images are needed to be sure about its occurrence. The front edge is not well defined.

In this 70 minute movie, multiple jets are seen in the north polar region, suggesting dynamic small-scale magnetic rearrangement.
