2017-08-12T14:10:09 --> 2017-08-14T13:20:09

A coronal hole of predominantly positive polarity that seems to extend all the way to the pole; effectively making it an extension of the polar coronal hole. The spread of the coronal hole suggests that it is created by the decay of the trailing polarity of an active region.

2017-08-10T00:00:09 --> 2017-08-11T09:50:09

A large coronal hole of predominantly negative polarity (red magnetic field contours). This coronal hole seems to be disrupted by some positive polarity elements (green) in the middle of its area - this makes the field lines to close with nearby negative patches (pink composite of 211A, 193A and 171A channel) and thus disrupt its area of open field lines.

2017-07-26T09:29:42 --> 2017-07-26T09:37:50

This event was impulsive and showed nice flare ribbons, but barely reached the GOES B1.0 level.

2017-07-30T13:50:57 --> 2017-07-30T16:51:48

New flux emerging in the NW quadrant of the SJI field of view.\nSlit touches the region, but just barely.

Peacock tail and other small surges at the edge of the sunspot.

2017-07-14T16:59:38 --> 2017-07-14T21:40:34

Many eruptive events including peacock tails and jets around sunspot.

M2.4 flare GOES peak at 02:09UT. Slit crosses entire flare ribbon.

2017-06-21T00:00:09 --> 2017-06-22T14:00:09

This is one of the big objects that used to be called bright points. They indicate flux emergence in polar regions, although it is difficult to observe the magnetic field there.

2017-06-20T04:40:13 --> 2017-06-20T08:29:25

The eruption starts with coronal dimming to the north of the active region, followed by the formation of post-eruption loops around it. The associated CME indicates a flux rope (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20170620.063607.w040.v0323.p063&frame=10).

2017-06-19T15:40:13 --> 2017-06-19T17:00:37

This again occurred in AR 12664, spatially more limited than the event about 12 hours earlier. The associated unimpressive CME is http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20170619.170007.w016.v0327.p070&frame=6.

2017-06-19T04:05:25 --> 2017-06-19T06:10:13

This was likely to originate in AR 12664, which was still slightly behind the limb. The associated narrow CME is http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20170619.050007.w019.v0568.p069&frame=9.

2017-06-18T03:55:13 --> 2017-06-18T05:04:49

The origin is not clear because the lower part overlaps with a horizontal coronal structure at some height.

2017-06-16T11:15:01 --> 2017-06-16T13:45:01

This is a scale-down version of the eruption on 15 June 2017 around 09 UT. No clear coronal wave was seen. The associated CME was also more diffuse.

2017-06-15T08:35:25 --> 2017-06-15T10:05:25

The eruption appeared to originate in a region behind the limb as no flare was associated. The EUV wave was seen primarily to propagate along the limb, but there was a secondary diffuse component moving into the disk.

The corona above the limb seems to open up due to a non-explosive eruption that may mimic loop expansion.

2017-06-14T20:20:25 --> 2017-06-14T21:50:25

This minor eruption occurred in AR 12661, which had decayed to be a spotless region a few days earlier. The eruption gives an impression that it was initially suspended by overlying field.
