2012-12-18T22:00:03 --> 2012-12-20T00:00:03
Transequatorial loops brightens over time. The northen part of the loops end at an active region, while the southern part end in the quiet sun.

2012-12-19T01:00:03 --> 2012-12-19T04:00:03
Two surges from opposite sides of the same active region occur in succession.

2012-12-17T23:00:03 --> 2012-12-18T20:00:03
Some shallow funnel-shaped loops gradually rise and erupt, carrying with them some cool 304 (red) prominence material.

2012-12-18T10:30:03 --> 2012-12-18T19:40:03
Episodic flaring in AR causing brightenings.

2012-12-17T02:10:03 --> 2012-12-17T20:20:03
A large filament exhibited transverse oscillations and erupted. Work in progress by Hui Tian (CfA) and collaborators on the dynamics of this event.

2012-12-16T00:00:03 --> 2012-12-17T12:00:03
As a new AR appears on the east limb, loops expands outward like a gentle eruption, accompanied by many episodes of surges/jets from the AR.

2012-12-15T17:00:03 --> 2012-12-15T17:50:03
A collimated surge/jet on the southwest limb.

2012-12-15T18:20:03 --> 2012-12-16T00:00:03
A large coronal hole in the southern hemisphere with a dominant positive polarity (green). Near its north east corner, there is a minority negative polarity (red) forming some local bipolar fields.

2012-12-15T18:20:03 --> 2012-12-16T00:00:03
A small scale eruption from an acive region, causing flaring loops.

2012-12-14T18:00:03 --> 2012-12-14T23:25:03
Episodic formation of condensation at a position of likely separatrix surface with a sharp boundary of 171 emission, indicating a large gradient of temperature and/or density. The condensation slides down loops as coronal rain.

2012-12-14T18:00:03 --> 2012-12-15T01:50:03
A beautiful loop-shaped prominence eruption on the east limb.

2012-12-13T22:00:03 --> 2012-12-14T10:00:03
A long filament (red, 304) residing inside a coronal cavity (seen at 211 in green) erupted causing a two-ribbon flare with elongated ribbons. Note that only the southeast and northwest portions of the filament within the filament channel erupted.

2012-12-14T02:30:03 --> 2012-12-14T12:40:03
A filament erupted and most of the material fell back to the Sun.

2013-02-13T16:30:03 --> 2013-02-13T23:50:03
A combination of drainage along field lines and in-situ heating may have contributed to the gradual disappearance of this filament (seen in 304, orange).

2013-02-13T05:50:03 --> 2013-02-13T11:30:03
The concave morphology of the quiescent filament roof-top suggests the existence of a magnetic flux rope above the filament.

2013-02-12T20:20:03 --> 2013-02-13T06:50:03
The first eruption leads to the appearance of a post-eruption arcade. As the arcade loops start to fade, another filament from the region is launched. It is difficult to establish a direct causal connection between the first eruption and the destabilization of the second.

The eruption seems to impulsively generate a shock that propagats ahead of the rising filamentary material.
