Planet Mercury transited in front of the solar disk over a duration of more than 5 hours (about 12:30 to 18 UT). IRIS took a closeup view of this entire course and followed the Mercury position over time. High-resolution images and spectra were successfully taken in a meticulously planned sequence. These observations can provide unique characterization of the IRIS its point spread function.

This sizable hedge-row prominence on the northeast limb shows interesting vertical/elongated threads and down flow dynamics.

AR 12750 emerged very quickly. This was the first IRIS observation of the active region via HOP 307. The out two very small sun spots both decay away within 4 hours of this first observation. The middle region does come together to form a more prominent, but still small, spot. It too decays away shortly after.

2019-11-02T12:41:05 --> 2019-11-02T13:53:39
The goal of this observation was to capture this small sunspot. Despite the fact that the pointing was off the SJI imager captured some interesting evolution of this small sunspot in the emerging AR 12750.

IRIS tracked AR12751 in coordination with GREGOR from 7-13 UT October 29 - November 1. This is the first pointing and contains many small explosive events and evidence of emerging flux under the slit.

2019-11-01T21:30:01 --> 2019-11-01T22:44:25
This appears to start in a localized region, which also shows post-eruption brightening. No associated CME is found.

2019-10-31T09:15:01 --> 2019-10-31T10:29:25
Very faint eruption that needs extreme scalings or difference images to see it. This was probably a backside event. It looks like developing to a CME (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20191031.102407.w021.v0195.p260&frame=5). A similar pattern (faint eruption - narrow CME) was observed also around 08:00 and 15:30.

Another example of a polar jet that seems to involve cool filament material.

2019-10-29T14:55:13 --> 2019-10-29T15:55:13
This appears to involve a mini-filament.

2019-10-28T03:10:13 --> 2019-10-28T05:00:37
A prominence is seen to erupt, reaching a certain height, but there is no sign at 211 A that the overlying corona is affected. This is likely a confined eruption, and indeed there was no CME.

2019-10-27T18:25:13 --> 2019-10-27T20:06:01
This gives an impression that the eruption started above the bright loops. There was no associated CME.

2019-10-26T11:40:13 --> 2019-10-26T13:10:13
We see two jets. Did the first one lead to the formation of a temporary mini-filament, which triggered the second jet?

2019-10-26T09:30:01 --> 2019-10-26T10:40:49
This started as an ejection of cool material in helical motions and then followed large scale structures around what looked like a flux rope.

2019-10-25T17:15:01 --> 2019-10-25T18:30:37
This event took place in a quiescent region at high latitude. The motion was highly non-radial. 304 A images indicate the presence of a small filament and cool material in the body of the jet.

2019-10-24T15:35:25 --> 2019-10-24T16:45:01
This occurred in a quiescent region (no AR anyway). The trajectory seems to be affected by adjacent coronal structures.

A cavity on the north west limb expands and moves southward. Note a faint cavity from the same location that exhibits the same behavior.

This AR exhibits an inverse polarity orientation (as compared to the hemispheric rule). This fact, combined with the high latitude of this AR suggests that Cycle 25 has just started

Prominence bubble occurring in a late stage prominence.

The filament is clearly observed in the Mg II h/k raster image. It is not visible in SJI images. The filament is located in the centre part of the raster image.
