The second of three studies of the coronal rain above AR 12615. We again see the loop structure above the active region, with material streaming from the tops of the loops back to the solar surface. After the SAA the slit crosses a newly-formed loop at both legs, meaning the material is falling 'through' the slit.

As AR 12615 passed over the western limb and off the disc, it showed some spectacular coronal rain. In this event there are three main loop-like arcades, with the IRIS slit just catching the top of two of them. Towards the end of the sequence the southmost loop empties, leaving just two loops. This was the first of three orbits during which this event was studied.

Tornado-like prominences have shown some evidence of rotation from previous observations, however when observed in Mg II by IRIS we see a different story. This channel shows a much more horizontal structure, where the column-like structure (seen in AIA 171 context) is not visible. The question is still open about the true nature of these events, and observations like this will help answer these questions and constrain models of these intriguing events.

2016-12-07T17:14:52 --> 2016-12-07T18:08:01

A bubble appears to move upwards in a prominence on the west limb. The bubble is seen clearly in the Mg II filter, with the slit crossing the bubble as it appears.

During a study looking for explosive events, running a sit-and-stare on AR 12615, a small B class flare went off, and the flare ribbon crossed the IRIS slit. This is an extremely high cadence observation of a flare.

A small microflare with nice flows seen in the spectral data.

2016-11-07T08:06:16 --> 2016-11-07T08:19:16

A small microflare is observed, unfortunately the spectrometer slit misses the event.

2016-11-06T07:48:19 --> 2016-11-06T08:04:33

A small eruption, unfortunately missed by the spectrometer slit.

2016-11-04T18:57:01 --> 2016-11-04T19:10:24

This observation exhibits strong and dynamic line broadening at the boundary of a coronal hole in transition regions lines, particularly Si IV

2016-11-04T11:49:15 --> 2016-11-04T11:53:16

Small brightening are observed along the slit. These brightening are accompanied by clear line broadening in the Ca II and Si IV lines.

2016-11-03T19:48:47 --> 2016-11-03T20:19:45

Very small flare. Spectrometer slit misses the majority of the flaring.

2016-11-03T12:46:42 --> 2016-11-03T13:51:51

A series of explosive event observed in quick succession. Spectrometer slit does partially cross some of the events.

2016-11-03T14:25:55 --> 2016-11-03T15:26:26

Loops on the limb are observed, as well as coronal rain along the loops. The spectrometer slit does not cover the loops.

2016-11-03T16:45:35 --> 2016-11-03T17:13:13

A small microflare was observed. The spectrometer slit passes over the event at the time of its peak activity.

2016-12-17T16:20:06 --> 2016-12-17T22:40:06

Synchronous activities were observed from two distanced active regions.

2016-12-17T23:40:06 --> 2016-12-19T00:00:06

A flux emerging region was observed in the on-disk coronal hole (near the boundary). The emerged flux then deveoped connections with the surrounding small-scale fluxes.

2016-12-15T03:23:06 --> 2016-12-15T04:07:06

A failed eruption was observed at the west limb. Wave-feature was observed propagating across field lines. A flux-rope like structure was also observed to raise and fall back.

Possible sympathetic filament erutpions were observed with sepeartion about 8-10 hours.

2016-12-15T18:57:06 --> 2016-12-16T00:00:06

A filament went unstable and erupted at last. Most of the filament material seems fall back to the Sun and lead to brightenings. The large-scale field might be changed due to the eruption that leads to a fast shrink of a coronal hole east of the source region. Moreover, there are synchronous activities from an active region at the west limb.

2016-12-14T18:16:06 --> 2016-12-14T18:46:42

a coronal jet was observed in the northern coronal hole with mini-filament eruption. The brightening after eruption showed an S-shape.
