The central paprt of an initially streamer-like structure seems to dim. The foot points of this structure is probably just on the limb, north of AR 12595.

2016-09-21T08:50:22 --> 2016-09-21T10:10:22

The northern part of the region is seen to erupt, causing temporary dimming in the overylying corona and the disk region toward north east.

This event is clearly seen in intensity images especially in 193 A channel, but for clarity a movie of running difference images is given. At least during 20-22 September 2016, there were more jets in the north polar region than in the south polar region.

This is from the far side. Successive jet-like ejections are seem to be deflected toward the equator.

Single emerging bright point results in series of small faint, jets. Final jet appears to reconnect to a point to the north, which brightens substantially.

IRIS observed a M1.1 flare in AR 12192, which was the largest AR since November 1990. The flare forms a single ribbon, which is short lived, along the right edge of the coronal hole. Seeming independent of the flare, a repeating jet flickers in and out of existence. However, the brightest jet occurs after the flare. Both before and after the flare the region shows many small scale brightenings.

IRIS observes three flares (C5.1, C9.7, and X1.0) in AR 12192, which was the largest AR since November 1990. The flares occurred in order of increasing intensity with approximately an hour between events. The lower intensity flares mostly miss the slit, however, the X1.0 flare does cross the slit. Most of the X1.0 flare's evolution occurs off the lower left corner of the observation, however, some of the brightening propagates slowly in the lower left corner. Both 1300 Å and 2796 Å show the flare activity; however, 2796 Å also shows oscillations in the coronal hole. Finally, the spectrum shows a strong increase in continuum emission after peak intensity in the X1.0 flare.

IRIS observes a GOES X3.1 flare in AR 12192, which was the largest AR since November 1990. The flare occurs within the first few frames of the observation and crosses the slit. The flare's brightness comes from two ribbons, which are roughly parallel. After formation, the two ends of the larger ribbon pivot downward in the image towards the coronal hole in the bottom left. However, some structure near the center of the larger ribbon prevents the central part of the ribbon from capping the coronal hole. This is clearly seen in 1330 Å and 2796 Å, however, 2796 ?Å shows faint absorption flows following the flare not easily visible in 2796 Å. In the spectrum Fe XXI shows broad emission near the flare's end.

A non-GOES sub-flare in AR12592 presenting as a crescent-shaped brightening across the FUV 1330/1400 slit-jaw channels. A round lingering brightening at the northern end of the intensification persists for at least an hour after peak intensity. This event precedes a GOES B1.8 flare observed in the same location minutes after the end of the this observation.

IRIS observes a GOES X1.6 in AR 12192, which was the largest AR since November 1990. The flare originates from three separate ribbons. The two ribbons near the coronal hole quickly become one ribbon (~2 frames). The combined ribbon spreads out, capping most of coronal hole. As the two remaining ribbons subside, material flows between the two regions. During the flare, the Fe XXI shows broad line emission. In addition, strong lines like, Mg II h&k and Si IV, show red asymmetries.

Active region jet on the northern plate of AR12591. It appears as a broad stripe of optically thin material extending from a bright, somewhat round footpoint. It only appears in the FUV 1330/1400 slit-jaw channels.

A sudden, energetic injection of material into the overlying magnetic structure above an active region on the west limb. The eruption appears as a rapid, curving flow of material with a bright footpoint. The presence of SAA makes it inconclusive whether this material escaped from Sun.
