The faint filament in the bounding box is seen to rise but it's unclear whether this was an eruption.

The filament material (304) seems to be contained in a sheath around a light-bulb shaped void, suggestive of a magnetic flux cope.

2018-01-15T00:54:44 --> 2018-01-15T01:07:37
Small, elongated, transient brightening observed on the trailing edge of AR12694. Spectra shows intensification and broadening of C II 1335 lines, Si IV 1394/1403, and Mg II h/k consistent with UV Bursts. The absence of O IV 1401 emission suggests the event takes place in the lower atmosphere.

Small, elongated, transient brightening along the eastern edge of the central plage structure of AR12694. Spectrum shows strong intensification and broadening across all strong UV lines sampled by IRIS, including the relatively weak O I 1355.6 and C I 1355.8 lines.

2018-01-11T17:26:17 --> 2018-01-11T18:07:53
Small, compact brightening near slit center observed in a mid-latitude coronal hole. Spectrum reveals a profound enhancement of Mg II h/k winds similar to enhancements produced by Ellerman Bombs in H-alpha.

Umbral flashes in 2796 and running waves in 1400 seen in the leading pore of AR12694.

2017-12-23T08:44:12 --> 2017-12-23T09:15:31
A very small flare was observed at AR 12692. The left part the active region was slightly active around the observing time. IRIS tracked this region from the east limb to the west to study on the evolution of the active region.

2017-12-22T05:24:50 --> 2017-12-22T05:51:51
Same as the previous one, but a larger jet was observed in the active region.

2017-12-21T22:41:21 --> 2017-12-21T23:29:51
AR 12692 produced many brightenings and small jet-like features. The right sunspot is a newly-emerging region around the observing time.

2017-12-21T14:52:22 --> 2017-12-21T15:09:34
A brightening was observed in a plage close to the west limb. IRIS tracked this region for 2 weeks from the east limb to the west. This small explosion was the "largest" phenomenon of this region in the latter half of the IRIS monitoring.

A plage region tracked between 2017/12/31 and 2018/01/08 forms a filament (OBSID 3610108077). The filament appears in the core of the Mg II 2796 line.

2018-01-08T18:12:06 --> 2018-01-08T18:14:33
Decayed plage tracked across the disk produces an eruption. The eruption occurs when a small amount of flux emerges in the northern extent of the decayed plage.

2018-01-09T03:30:09 --> 2018-01-10T00:00:09
A small coronal hole in the north hemisphere of the sun. Note that it is primarily composed by positive polarities (green color in HMI magnetogram).

2018-01-09T03:30:09 --> 2018-01-10T00:00:09
A highly non-radial confined eruption seen at the north east limb of the sun. A (potentially) polar crown filament becomes unstable and keeps gaining height until it reaches a certain altitude and halts to expand. Cool dark material is seen to be lifted with this "bubble" like structure.

The north coronal hole extends southward. Note the activity inside the hole in the form of bright points and small bright loops.

A jet eruption at the south pole of the sun. Note the dark material moving from east to west while a jet-like column brightens.

A failed eruption originating from AR12693. Note the large scale connectivities associated with the developing eruption. There was no CME originating from this AR.

The base of the jet stays bright in both 1330 and 1400. When the slit nears the limb, the jet leaves the bright base.
