2017-04-20T18:00:09 --> 2017-04-20T22:00:09

A concave structure, probably representing a flux rope, is seen to form above the prominence during the eruption. This is seen most clearly in 171 A channel.

The flare lasted long, and as expected, was associated with a more decent CME than the previous flare. This one does not show clear coronal waves, and the expansion was more in the radial than horizontal directions. After the peak downward motions are seen from the top of the arcade which is hot. Shortly after the eruption, big motions were seen, but these are image motions. Indeed, the peak of the flare coincided with AIA weekly calibration.

Eruptive C3.3 flare and coronal wave (Coronal Wave)

AR 12644, which produced M-class flares on 1-2 April 2017 came back as AR 12651, producing two C-class flares on 18 April 2017. The first one was associated with a mediocre CME, but it accompanied a coronal wave propagating along the limb (counterclockwise) and into the disk.

Three eruptive flares (Eruption)

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.

Large-scale coronal propagating front from non-AR and no-flare (Coronal Wave)

2017-01-19T09:45:01 --> 2017-01-19T10:30:37

This may be the first coronal wave we have observed since late October 2016. It is minor, but still disturbs a large area to southwest. No active region or flare is associated. No CME either.

Filament Eruption at the East Limb (Filament Eruption)

2017-01-12T15:35:09 --> 2017-01-12T18:03:09

A filament eruption is observed near the east limb. The eruption caused reconfiguration of the surrounding coronal loops. Loop oscillation is also found during the process.

This movie shows coronal activity of AR 12621 before it made into the NOAA database. It was registered to have the spot aera of 10 msh at 27 December 2016 00:00 UT. It grew to 30 Msh the next day, but the coronal activity was less spectacular then. To Ryan: This should bbelong to the object AR. But as we communicated in November 2016, the object window for AR is too big and clumsy for the annotator to close properly. I think the problem I reported yesterday was the same thing as I did in November 2016.

Major eruption, perhaps Earth-bound (Filament Eruption)

2016-11-05T03:00:06 --> 2016-11-05T07:00:06

Only the northern part of the filament is seen to erupt, but the main eruption should be in the plage region immediately northeast of AR 12605. The CME observed by LASCO assumes a complex shape, indicative of different magnetic structures. See a halocme tweet on this event: https://twitter.com/halocme/status/794782739987832832

Large Filament Eruption and Post Brightenings (Filament Eruption)

A large filament erupted from the northern hemisphere. About 10 hours later, a large area to the east of the erupted filament showed brightenings but without filament activities associated with them. There was another filament eruption near the west limb at the same time of brightenings. The brightenings seem to be associated with a CME observed by LASCO.

This eruption took place in a non-spot region to the east of AR 12593, accompanied by a gradual flare with the peak GOES flux of B6.2. The movie shows the locations of the flare ribbons and post-eruption arcade. The dimming region is extended to far south. The event was tweeted in near real-time (https://twitter.com/halocme/status/779207319598960640).

Several eruptions occurred near the west limb. Most of them are from AR 12568(?). The disturbances from the eruptions seem to cause a filament eruption to the south at last.

Two flares are observed close in time from AR 12565. The first one seems non-eruptive and the second one released large amount of material into the corona. Part of the filament material came back after the eruption.
