A small flare on AR 12808 is seen through kernel-like brightenings in the SJIs. Most of the flare is out of the field of view, but some parts are seen in the top of the image.

As AR 12808, there was a surge-like event rising from a hot loop, with an accompanying jet and eruption. The same region seems to recur both earlier and later, but this interval it was at its strongest.

A small eruption on AR 12808 as it rotates into view. The round, loop shaped eruption is seen in all SJIs as a larger cooling loop / coronal rain nearby gradually disappears.

This was another episode of flaring activity and peacock tail in AR 12804 (as it approached the west limb with the solar rotation), especially in its trailing polarity (near the upper left of the movie). The peacock tail appeared as some episodic brightenings of an arcade of coronal loops on the lower-right edge of this trailing polarity. The brightenings appeared to propagate from lower loops to higher loops along the axis of the arcade (perpendicular to individual loops). The peacock tail occurred before and after the moderate flaring that peaked at about 00:11 UT.

When (AR) 12804 approached the west limb with the solar rotation, there were some minor to moderate flaring activity, especially in its trailing polarity (near the upper left of the movie). More interesting were the peacock tails (marked by the box), some episodic brightenings of an arcade of coronal loops on the lower-right edge of this trailing polarity. The brightenings appeared to propagate from lower loops to higher loops along the axis of the arcade (perpendicular to individual loops).

Episodic coronal rain and surges were seen in AR 12804 when it was just over the west limb. One episode of coronal rain was the most intriguing: it started at about 16:00 and grew to the maximum at about 16:10-16:15 to take shape of an arch, and gradually disappeared by 17:50. In the literature, such rapid growth of coronal rain could be associated (post-)flare loops, and some of them may be long-lived and were also called "arch filament", seen in H-alpha.

This prominence exhibited active flows, mainly along an arch-shaped trajectory. There were also episodes of possibly helical flows. Over time, the continual flow drained and depleted the mass in this portion of this prominence. Prominences are known to disappear, either via dramatic eruption, or via gradual drainage. The latter seems to be the case for this portion of the prominence here.

Interesting arch-shaped flow patterns in this prominence at the SW limb. There was also a high branch of prominence threads extending to the north at greater heights, showing signatures of counter-streaming flows, some downward and some upward.

2021-03-19T23:00:09 --> 2021-03-20T07:00:09
This event lacked clear markers of eruption, apart from slowly formed and spreading flare ribbons or post-eruption arcades. But it was a quite big CME ( https://cdaw.gsfc.nasa.gov/movie/make_javamovie.php?img1=lasc2rdf&img2=goesx&stime=20210319_2100&etime=20210320_0700 ).

This event was more easily noted with the formation of a post-eruption arcade over long time. Need a detailed analysis to pin down where and how the filament erupted. Thos one accounts for the CME going southeast ( https://cdaw.gsfc.nasa.gov/movie/make_javamovie.php?img1=lasc2rdf&img2=goesx&stime=20210322_0000&etime=20210322_0700 ).

This flare developed slowly, and perhaps lacked strong non-thermal emission. But a post-eruption arcade formed, and was associated with a decent CME appearing in northwest (https://cdaw.gsfc.nasa.gov/movie/make_javamovie.php?img1=lasc2rdf&img2=goesx&stime=20210322_0000&etime=20210322_0700). The CME coming from southeast is a separate event.

Two minor eruptions around the same time. Likely independent, but who knows?

This jet may be characterized by quick spread of footpoints. The footpoint brightening is subdued.

Same comment as the previous event applies (althoug in a different region): An eruption from a tiny sigmoid region. Altough not traveling long distances, the EUV wave was quite notable for this magnitude of eruption.
