2013-07-20T09:00:03 --> 2013-07-20T21:00:03

Prominence on west limb is activated, but the material doesn't lift off. Instead, it travels mostly parallel to the photosphere across a large distance (60 degrees or so) to the north.

2013-07-22T03:45:04 --> 2013-07-22T13:30:04

A small bipole emerges within a (-) coronal hole, and isolated flux of the opposite (+) polarity is left over and forms a localised region of coronal emission ehibiting a divergence point over the (+) flux.

Swirlimg material within the western portion of a south polar-crown prominence.

2013-07-22T01:45:03 --> 2013-07-22T04:55:03

An upward surge of filament material behind the N-pole. It appears to be a 'failed' eruption.

2013-07-22T00:00:03 --> 2013-07-22T10:00:03

AR 11801 emerging over the East limb. The occurrence of rapid loop reconfiguration and chromospheric mass injection into the corona is evident.

2013-07-22T00:00:03 --> 2013-07-22T07:25:03

Behind-the-limb surge of filament material poleward.

2013-07-21T17:45:04 --> 2013-07-22T06:50:04

Diffuse over-lying loops to the north east move north-west, and this is followed by a localised brightening in the center north region of the FOV. A reconnection/reconfiguration front moves west. and then south, curving around the large filament in the center-south of the field of view.

2013-07-21T14:40:03 --> 2013-07-21T15:50:03

Two coronal jets occur at the same time. Probably confined to the two legs of a bipolar loop structure..

2013-07-21T13:20:03 --> 2013-07-22T03:40:03

Swirling material within a quiescent filament. Turbuklent vortex? Complex filament magnetic field?

2013-07-21T20:30:03 --> 2013-07-21T22:38:03

The same filament lift-off as before, but showing the cooler chromaspheric component in comparison with the hotter coronal component. The material seems to be quite diffuse, with the majority of the plane-of-sky area of the eruption being the hotter component. Perhaps this is why the erupting material seems to buoyant. The eruption is rapid and very little falls back to the surface.

2013-07-21T20:50:03 --> 2013-07-21T22:25:03

A possible polar-crown filament lift off at a near-perfect north-ward trajectory. The event likely occurred well beyond the West limb at >45deg latitude. There does not appear to be any pole-ward deflection, but this may be a LOS effect. There appears to be a large cavity-like structure in the coronal region where the eruption took place. This may have allowed the eruption to exhibit the uncommon trajectory.

2013-07-18T16:48:03 --> 2013-07-18T22:12:03

Loop tops oscillate in response to an eruption nearby. The oscillations are rapid and many periods can be seen. The second eruption happens when the loop tops still oscillate, and seemingly disturbs the loops much less than the first one.

Large prominence eruption on the W limb.

2013-07-18T16:30:03 --> 2013-07-18T22:06:03

Large eruption on the limb, followed by rapid ejection of plasma in a second eruptive event. This is a second eruption from the same location on the E limb in the last several days. It appears to be a part of sequence of eruptive events, mostly of smaller magnitude.

A minor surge on the limb.

2013-07-18T15:36:03 --> 2013-07-18T17:21:03

Another two minor activity events. The reason I'm marking them is because there appears to be a sudden burst of activity all over the limb, which ended with a larger eruption on the E limb.

2013-07-18T14:12:03 --> 2013-07-18T15:51:03

A minor filament activaion. I'm only annotating it becase it appears possible that it is a part of larger sequence.

Nice example of coronal cells (see Sheeley & Warren 2012 ApJ 749 40) located between a coroanl hole and a large north-south filament. Sheeley et al (2013 ApJ 772 88) argue that the direction of the horizontal field along the filament channel can be inferred by the properties of these coronal cells.

A pretty filament eruption on the E limb.
