2018-04-20T04:50:09 --> 2018-04-21T03:30:09
A small filament erupts as a result of flux cancellation. The flux cancellation continues after the event.

A filament erupting in the southwest quadrant of the solar disk. A narrow angle CME was associated with this event (http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20180417.072424.w122.v0404.p159&frame=4&r&cor2=a)

An ephemeral region emerging in the southwest quadrant of the sun. Green colors show high temperatures of 2 MK.

A solar prominence (dark material) suspended in a coronal cavity. Here, the "envelope" of the the highest lying parts of the prominence mark the lower side of a coronal cavity.

2018-04-14T06:20:09 --> 2018-04-15T10:40:09
A decaying active region in the northeast quadrant of the solar disk as seen in three different wavelengths (304 A: T=50kK; 171 A: T=0.6 MK; 211 A: T=2 MK). Note the magnetic flux distribution on the surface (green positive, red negative flux). A filament is seen as a dark feature in 304 A (diffuse s-shaped feature; top left panel).

2018-04-10T16:41:24 --> 2018-04-10T17:23:32
Small surge with material visible above the west limb. Slit catches both the eruption and material above the limb.

A minifilament eruption on the southeast quadrant of the solar disk (solar limb on the left). The interesting thing here is that there seems to be a shock bubble associated with this eruption.

This region had the number of 12703 only on one day, April 1, 2018 with the spot area of 10 MSH. It has been spotless since then, producing only minor activities. Note the formation of a sigmoid region to the east, which was also sluggish.

This is so diffuse that it can be seen only in difference images. In this field of view at least something was ejected into the heliosphere.

Slow eruption from the AR 12703 remnant. The big sigmoid to the east of this eruption somehow stayed intact.
