Thanks to STEREO we were able to begin tracking this AR as soon as it came around the east limb. It was tracked via HOP 307 from limb to limb.

Both a prominence off the east limb and part of small filament were captured via a large dense raster. This OBS was run twice, each with a few repeats, throughout the day.

This small region of emerging flux came and went in a couple days and produced multiple explosive events.

The eruption occurred in what could be considered a coronal bright point (although it was largish). The area south of the region dimmed temporarily.

A slow, plasmoid- or flux-rope-like eruption was seen exclusively in 171 A images. The ejecta was seen to deflected toward the equator.

The eruption likely occurred on the backside. It appeared to trigger another one to the north on the visible side.

This jet contains cool material initially ejected in helical motions.

A bipolar region hosted what looked like a coronal bright point in full-disk images. It lasted a few days. Its appearance traced the evolution of the underlying magnetic field structure.

A tiny eruption, causing the overlying structure to slightly dim.

This eruption was very diffuse and seen only in 171 A images. An ourflow seemed to precede a more localized filament eruption, which accelerated the eruption of a closed coronal structure. The eruption was deflected clockwise.

2019-05-21T06:45:01 --> 2019-05-21T09:01:01
The coronal structure overlying AR 12741 was seen to gradually open up and dim, even though eruption itself was not clearly seen. This was associated with a CME (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20190521.083607.w041.v0323.p248&frame=12).

2019-05-21T04:00:09 --> 2019-05-21T06:10:09
Low-lying filament activity around AR 12741 seemed to cause a minor eruption, which did not go beyond the AIA field of view, hence no CME.

This looked like a narrow eruption, different from a flux rope eruption (CME), but it started impulsively, causing the overlying structure to oscillate.

This was probably a confined eruption, but the overlying structure was seen to be disturbed.

Evem though this was on a relatively small scale, it was probably an eruption of a flux rope, seen in dark to the north of the region in projection. A surge followed the eruption, propagating in SWW.

This happened in a quiescent region. The wave propagated preferentially in the northwestern direction. No flare was seen above the ~A8 beckground level.

Large-scale structure overlying AR 12741 is seen to gradually open up. This may be related to the slow CME observed around 12:00 (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20190518.120007.w041.v0170.p256&frame=19).

A small filament erupted, but it had far-reaching effects high in the corona for the outflow to be visible over the limb.
