2018-08-25T12:45:01 --> 2018-08-25T14:01:01
An reversed sigmoid (expected in the northern) erupted on a much smaller scale than those that result in big CMEs. In a reduced resolution the eruption may look like a bi-directional jet.

2018-08-24T02:30:01 --> 2018-08-24T10:30:01
There were no direct eruptive signatures, but a relatively large volume was filled with what looked like a post-eruption arcade.

2018-08-23T08:00:09 --> 2018-08-25T08:00:09
An anti-Hale region emerged on 23 August 2018. It did not produce much activity beyond B-class flares.

2018-08-23T15:20:25 --> 2018-08-23T16:40:25
The eruption was seen without a clear dark filament, but it produced spreading ribbons as is often the case with larger eruptions.

2018-08-22T11:45:01 --> 2018-08-22T13:00:37
The origin seems to be the following part of AR 12719. Probably no CME associated with this kind of events.

A jet was seen in the eastern end of the following part of AR 12719. It temporarily dimmed the overlying structures.

Eruption from the decaying active region NOAA AR12718. It most likely was a failed eruption since no indication of a CME was seen in LASCO images.

2018-08-18T16:30:09 --> 2018-08-19T04:10:09
A filament seen along its axis surrounded by a cavity. This eruption was captured by LASCO and produced a CME of 480 km/s (see http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20180819.074807.w010.v0489.p217&frame=3&r)

2018-08-18T20:50:09 --> 2018-08-19T19:10:09
A long north-south oriented filament on the north hemisphere of the sun. The filament forms along the neutral line (between positive (green) and negative (red) polarities)

2018-08-18T20:50:09 --> 2018-08-19T19:10:09
Four consecutive eruptions seen at the east limb. These eruptions showed no imprints in the LASCO coronagraphic data, thus they were failed eruptions.

2018-07-31T01:20:09 --> 2018-07-31T12:10:09
A filament eruption was observed near the equator. It seems that majority of the filament material falls back to the Sun showing multiple brightenings.

Small eruption from a bipolar region. The eruption influenced a larger area around the source region (showing temporary dimming).

This movie does not show the feature. It exists in the wings of Mg II and can be observed by clicking on the MgII_raster on the IRIS observation page. Counter streaming is easily observed almost perpendicular to the IRIS slit.

This Flare does not have a corresponding GOES event. The IRIS slit crosses the event near the beginning and end.

The IRIS slit raster across a bright point in the middle of AR 12717 around 05:58:00, at the same time enhancement of continuum are observed in Si IV, C II and Mg II h&k.

The IRIS slit raster across a bright arc at the north end of AR 12717 around 05:08:00 and extensively widened wings are observed in Si IV, C II and Mg II h&k.

Cool material (yellow: 304A channel; 50,000 K) is seen to move along the north south direction filling magnetic field structures above the west solar limb.
