2019-02-17T09:50:09 --> 2019-02-18T05:50:09
A filament in between the two dispersed magnetic polarities of a decaying active region. The filament is visible as a dark lane between the green and red patches (positive and negative magnetic polarities).

A Coronal Cavity at the northwest limb of the sun. Cool material (white/purple) extends high all the way to the core of the cavity. Red colors show emission from plasma at 2 MK.

Some prominence materials are noticed to fall along a bubble at the base of the prominence.

There is a bubble located at the base of the prominence. Interestingly, a second bubble appears beside the previous one, and rises up into the prominence, and finally breaks.

Part of the prominence appears to be twisting/untwisting, as suggested by the relative motions of the prominence materials. A slit of IRIS happens to scan that region and may provide more detailed information about the motions of the materials there.

2019-02-09T22:25:30 --> 2019-02-09T23:02:22
A dense and thick prominence extends high up into the solar corona. Based on the tracking of this prominence, what is shown here likely corresponds to the eastern leg of a large prominence.

A coronal cavity in the northwest limb of the sun exhibiting rotational motions in its interior. It appears that material rises from lower heights and as it moves upwards within the cavity a sense of counterclockwise rotation occurs wirhin the cavity.

Prominence is a bunch of dense and relatively cool ionized gases suspended in the solar corona. The video shown here is from IRIS observation. It displays both horizontal and vertical flows inside the prominence, implying the ongoing dynamic and complex processes there.

An on-disk filament (dark feature) is seen to extend past the solar limb as the sun rotates, essentially becoming a "prominence" (term used for filaments when they are appear to protrude past the solar limb). The filament/prominence is seen along its axis, making it appear as a radial structure. Note the swaying motions of the filament.

This was of backside origin. A diffuse but broad front is seen in 211 A images.

Another example of coronal rain observed by IRIS (e.g. http://www.lmsal.com/solarsoft/irisa/data/level2/2019/02/01/20190201_061304_3610108077/www/l2_20190201_061304_3610108077_SJI_1330_t000_fits_20190201_061304_j.html). This one outlines closed structures, seen in 171 A images in addition to 304 A images.

In 304 A images, we see the coronal rain against tall loops in 171 A. This is the same coronal rain observed by IRIS (e.g. http://www.lmsal.com/solarsoft/irisa/data/level2/2019/01/31/20190131_104409_3620108077/www/l2_20190131_104409_3620108077_SJI_1330_t000_fits_20190131_104409_j.html).

Three minor eruptions are noted in this movie. The northmost one was probably of backside origin. The associated small-scale brightenings are found on the disk for the other two eruptions.

QS/CH boundary observed for almost 11 hours on 2019/02/03. This observational sequence should coincide with the slit crossing the QS/CH boundary. There are 3 more observational runs before and after this sequence, covering QS, QS/CH boundary and CH.
