A set of small scale loops seen in 171 \\AA\\ harbors some cooling condensation seen as either coronal rain or a small-scale prominence, displaying active drainage.

2015-02-01T03:00:03 --> 2015-02-03T04:00:03
A small prominence (called a tornado by some researchers) in the polar crown region erupts, or more precisely, is displaced from one location to another. The coronal loops seen at 171 show substantial reconfiguration during this process, which took about two days.

2015-01-31T00:00:03 --> 2015-02-03T15:00:03
A sizable new filament on the east limb is rotating onto the disk. Its western end is adjacent to a flux emergence region still undergoing growth.

2015-02-01T10:00:03 --> 2015-02-03T15:00:03
A new flux emergence region near the east limb continues to grow in size, establishing coronal loops.

A surge seen at 304 \\AA\\ near the SW limb.

2015-02-01T01:00:03 --> 2015-02-01T16:00:03
A prominence on the east limb erupts, making an capital Lambda shape. Some material falls back down.

2015-01-30T12:51:03 --> 2015-01-30T14:02:03
An inverted-Y geometry showin a clear spine with sharp intensity contrast, possibly indicating large density/temperature contrast across it.

2015-01-30T12:51:03 --> 2015-01-30T14:02:03
A collimated surge/jet; most material falls back down.

2015-01-30T08:15:03 --> 2015-01-30T15:00:03
An interesting prominence eruption. There is a outer loop surrounding a bright core, both exhibiting bright 304 emission, indicating cool prominence material. The frontal loop portion has a significant portion of its material drained back to the Sun during the eruption, while the core did't erupt at all, but involving substantial mass flow.

2015-01-29T05:00:03 --> 2015-01-29T15:00:03
A coronal loop seen at 171 gradually rises and expands over the course of several hours, possibly indicative of some large-scale reconfiguration of the corona.

2015-01-29T06:30:03 --> 2015-01-29T10:15:03
A small-scale, so-called funnel prominence on the NE limb. It's characterized with 304 (red) cool material, constantly downflowing, located at the lower tip of funnel-shaped coronal loops seen at 171 (yellow). A preliminary survey of similar prominences can be found at: http://adsabs.harvard.edu/abs/2014IAUS..300..441L or PDF rom: http://sun.stanford.edu/~weiliu/research/publications/2013/2014IAUS_Liu_Berger_Low_funnel-prom.pdf

2015-01-29T06:30:03 --> 2015-01-29T10:15:03
A loop-shaped prominence erupted on the northeast limb (source region occulted). Most of the material was dispersed and fell back to the Sun.

2015-01-28T23:00:03 --> 2015-01-29T15:00:03
A large coronal hole covering a good fraction of the southern hemisphere is now rotating toward the Sun-Earth line. It has an unusual triangular shape, with a straight-line boundary on each side.

Two episodes of emerging flux to the north of AR 12269. The medium-sized bipolar region to the northwest of this AR emerges first, followed by another medium-sized bipolar region to the northeast. Much coronal restructuring occurs apparently in concert with these flux emergence effects.

A seemingly minor eruption in AR 12269 produces a clear coronal dimming to the vast area to the north.

The M1.1 flare in AR 12668 may be at first sight not very eruptive (in accordance with its impulsive soft X-ray time profiles). But it launched a nice coronal wave toward north to northwest, encompassing AR 12669 and AR 12671 in its propagation. Tweeted as https://twitter.com/halocme/status/559818090834182144.
