This is one of the best shots of hedgerow prominence observed by IRIS, which has beautiful, vertical structures. The material falls down slowly. Below the prominence, the structures are no more vertical, but somewhat horizontal or loop-like. Dark bubbles or plumes are not so clearly seen.

A plage at the east limb shows some small activities. Coronal rains are continuously observed in this region and a surge is captured by IRIS.

A bright feature can be seen in a plage in the C II and Si IV lines. An on-disk prominence is located at the same location, which is seen as a dark feature in the Mg II k3 line. High and low temperature plasma exist co-spatially.

It is possible to find at least some jet-like collimated eruptions in polar coronal holes within, say, 10 minutes of time-lapse images, but this one was quite obvious. It is accompanied by the ejection of cool material and also followed by a smaller jet at a higher latitude.

2019-02-25T18:30:01 --> 2019-02-25T19:40:49
This is a very small eruption that only temporarily shows dimming (in 211 A) and elongated two-ribbon brightening.

This originated in a small brightening around N22 E103, as confirmed in STEREO-A EUVI images, in which the jet-like feature is not easily identified. In AIA it appears in 211 A images, but not in 171 A.

A filament eruption originating from the single decaying active region transiting the solar disk. This was a successful eruption as it can be seen in the movie from LASCO coronagraph data (http://spaceweather.gmu.edu/seeds/dailymkmovie.php?cme=20190224&r)

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).

An emerging flux region (unnamed by NOAA) near the southwest limb of the sun.

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.

2019-02-09T09:19:04 --> 2019-02-09T09:48:17
Some prominence materials are noticed to fall along a bubble at the base of the prominence.

2019-02-09T07:16:00 --> 2019-02-09T08:12:14
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.

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 prominence bubble developing under a prominence seen in the northeast limb of the sun.

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.
