2017-04-01T20:20:09 --> 2017-04-02T00:00:09
A second eruptive flare (M4.4). In this event, the CME 'bubble' is rather evident in the low corona.

2017-04-01T16:20:09 --> 2017-04-02T13:30:09
A small parasitic bipole emerges by the following polarity of the large bipolar AR in the south hemisphere of the sun. This sparks some jet-like activity but the most striking feature is two occurences of Coronal Waves emanating from the following polarity (possibly due to the interaction of the two bipoles). The coronal waves seem to bounce off the south coronal hole.

2017-03-31T00:00:09 --> 2017-03-31T20:10:09
A large (extending to lower latitudes) coronal hole at the south pole of the sun.

2017-03-31T09:25:09 --> 2017-03-31T22:20:09
A large (bipolar) emerging flux region with some subflaring activity (possibly a confined flare towards the end).

2017-03-30T10:30:01 --> 2017-03-30T12:30:01
A jet was launched first closer to the limb, followed by what looks like a dual mini-filament eruption that was more non-radial in the beginning.

2017-03-29T02:30:01 --> 2017-03-29T07:30:01
This occurred in a quiescent region east of AR 12644. The trigger is not identified, but the disturbances ran from southeast to northwest. No clear ecvience that something erupted.

2017-03-28T04:30:01 --> 2017-03-28T06:00:01
Another C-class flare in AR 12645. An eruption coincided with the impulsive phase, but it was probably less powerful than the previous ones in the same region. There was no associated CME.

The prominence eruption was captured first in 304 A images, in which it was hard to trace it to higher altitudes. The eruption at later times was seen better in 171 A images. No obvious CME associated.

On 30 March 2017 we see two sunspot active regions, AR 12644 (north) and 12645 (south). AR 12644 already showed bright coronal structures close to the east limb on 24 March. It had the largest growth on 26 March in terms of the region size and transient activity (one C-class and many B-class flares). The emergence of AR 12645 was seen during the second half of 26 March. Its most active period was 27 March. As soon as both of the leading and trailing spots got established, both ARs became less active. They may not produce major events unless they are triggered from outside the ARs.

2017-03-27T16:30:01 --> 2017-03-27T19:30:01
There were three eruptions between 17:00 UT and 18:30 UT. First, large-scale motions seemed to precede the footpoint brightening of the C1.6 flare that peaked at 17:12. Then more violent eruption was seen associated with a B4.1 flare peaking at 17:43 (here it seems that flare=post-eruption arcade) slightly closer to the limb. Finally the footpoint brightening of theC5.1 flare that peaked at 18:20 seemed to precede an eruption, which appeared not as significant as the first two. The SEEDS catalog does not contain LASCO images around these events, but a CME is seen in https://cdaw.gsfc.nasa.gov/movie/make_javamovie.php?img1=lasc2rdf&img2=goesx&stime=20170327_1800&etime=20170327_2359.

This flare occurred in a newly emerging region AR 12645. The eruption coincided with the flare impulsive phase, and the movie captures both the erupting flux rope and driven front. The corona above the AR was temporarily dimmed. The associated CME is http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20170327.121207.w047.v0180.p090&frame=19&r.

This probably came from slightly behind the limb, not affecting a nice thin structure (current sheet?) in the foreground.

This can easily escape detection, since it is slow and diffuse. It is seen only in 304 A images. Such an eruption may not be related to a CME.

The eruption was mostly in the southwest direction (in image plane) and we see some mild effects there (dimming, chromospheric brightening, etc.)
