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.

2018-04-12T00:00:09 --> 2018-04-12T04:47:39

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.

2018-04-10T00:00:09 --> 2018-04-10T13:40:09

Same as previously, but in a four panel view separating the wavelengths.

2018-04-10T00:00:09 --> 2018-04-10T13:40:09

Recurrent eruptions (three?) near the solar disk center that seems to be associated with cancelling magnetic features on the surface (red and green structures)

2018-04-01T12:06:24 --> 2018-04-01T13:13:46

A small flare is observed in 1330, 1400 and 2796 along with a filament eruption, the slit \ncrosses the flare region.

2018-04-08T10:30:09 --> 2018-04-09T04:00:09

A filament sitting quietly for a while. A part of it erupts in the end.

2018-04-09T02:30:09 --> 2018-04-10T00:00:09

Beginning of a small bipolar flux emergence is observed.

2018-04-01T00:00:09 --> 2018-04-07T00:00:09

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.

2018-04-06T04:40:13 --> 2018-04-06T06:00:13

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.

2018-04-05T13:30:01 --> 2018-04-05T17:00:01

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

2018-04-04T08:40:13 --> 2018-04-04T10:40:13

A mini filament (prrominence) eruption triggered a highly deflected jet.

2018-04-03T03:45:01 --> 2018-04-03T05:31:01

Initially looking like a jet, the ejected material traced closed field structure that was twisted.

2018-04-02T10:15:01 --> 2018-04-02T11:25:01

A small eruption causing temporary dimming. This appears to be driven by cancellation of sub AR magnetic field.

2018-04-01T15:50:25 --> 2018-04-01T16:50:25

This occurred in the northern part of AR 12703, where the magnetic configuration looked more or less open. The trajectory presumably reflected local magnetic field.

2018-04-01T03:00:09 --> 2018-04-01T04:00:09

A small but explosive eruption in the following part of AR 12703, producing short-lived double ribbons with dimming in between.

2018-03-22T02:09:26 --> 2018-03-22T03:35:38

AR12702 has rotated well over the limb. Just to the north of AR is the very horizontal prominence/cool loops structure.

2018-03-20T15:39:09 --> 2018-03-20T15:47:07

This is small spray from an active region at the limb. Very low period of solar activity.

2018-03-23T00:00:09 --> 2018-03-24T06:10:09

A coronal cavity at the east limb of the sun containing a prominence. The prominence undergoes an interesting evolution of its shape.
