The temporal evolution of a prominence on the W limb is observed. It looks like the prominence is slowly shrinking and disappearing. The slit is crossing the event.

On 26-Feb-2019 IRIS captured a prominence at the E solar limb. This observational sequence shows how prominences are formed. The slit crosses the event.

2019-03-02T01:10:13 --> 2019-03-02T02:45:01
The eruption followed slow rising motions of closed loops. As a result, a post-eruption arcade formed underneath the eruption and tgemporary dimming was seen in the area to the east.

2019-03-01T01:15:01 --> 2019-03-01T02:21:01
The eruption started from an inverse-S-shaped structure, much smaller than typical active region sigmoids. It affected areas west and southeastern to its origin.

2019-02-28T01:50:25 --> 2019-02-28T04:50:25
The weak eruption appears to be suppressed by an overlying large-scale coronal structure.

2019-02-28T00:10:13 --> 2019-02-28T01:00:37
An eruption from a bright region, which was not large enough to be an active region. A small filament was involved. This had no coronagraphic consequences.

This filament eruption occurred in a quiescent region. It is not clear what triggered it. But the CME-like closed loop structure was seen to move outward in two steps, more clearly in 171 A than 211 A.

2019-02-14T07:34:09 --> 2019-02-14T08:43:15
A hedgerow prominence gradually lifts off. You can see a sharp horizontal boundary moving up slowly.

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.

2019-02-14T02:53:17 --> 2019-02-14T03:50:38
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.

2019-02-17T11:49:56 --> 2019-02-17T12:38:25
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.

2019-02-26T22:10:13 --> 2019-02-26T23:10:13
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.

2019-02-25T19:30:01 --> 2019-02-25T20:30:01
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.

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