2012-08-07T00:00:04 --> 2012-08-07T20:00:04

A series of at least seven explosions in a smallish AR, just inside the SE limb, send out perturbation fronts into the surroundings, causing high off-limb loops to oscillate, and with visible couplings to regions at least half a solar radius away.

Chromospheric material from a filament rains down and warms up to near-MK temperatures.

A QS filament activates, and while it does not appear to erupt, there are clear signs of a post-eruption arcade (with moss-like expansion). Note a flux concentration to the NW which shows a fan deformation in the later stages of what appears to be an eruption. Also note the thermal changes (to ~1MK, blue) at the ends of the filament field where the material impacts the lower atmosphere).

Not exactly sure what is going on here - it appears a fiilament is attempting to interact with another filament, but instead gets mostly repelled by the concomitant coronal cavity of the target filament. The end result is a nice spiraling or swirling motion of the plasma throughout the interaction phase.

2012-08-04T10:00:04 --> 2012-08-04T18:00:04

Activation of an overtly twisted filament, with lots of emission in the 171 channel of AIA and copious amounts of apparent [un?]braiding, but surprisingly little change in the before/after states of the filament as seen in the 304 channel.

2012-08-03T00:00:04 --> 2012-08-03T20:58:04

A particularly nice example of a filament (or perhaps just a long sheared arcade) at the interface between the diffuse postive and negative fluxes, with flows along some strands rendering them above or below other, opaque strands.

Flows and opaque strands highlight 3D structure of this filament.

2012-08-02T09:22:04 --> 2012-08-02T13:44:04

A spray surge appears to start from underneath a filament. The surge appears to cause the dark blob of the filament wiggle around a little bit. There is a subsequent eruption on the limb, and given that the disturbed filament goes towards the limb, it is not impossible that the eruption happened on its other end.

2012-07-28T20:00:04 --> 2012-07-28T21:20:04

A small-scale eruption/flare triggers an EUV wave from an active region near the SW limb. This wave appears to perturb a slowly rising prominence nearby during its eruption. It is not clear whether this flare/EUV wave actually triggers the prominence eruption - but there is a timing coincidence between the two eruptions.

2012-07-29T00:10:04 --> 2012-07-29T04:00:04

A surge from an active region on the southern hemisphere erupts and is channeled by a transequatorial loop system of sigmoid shape to land on the northern hemisphere.

2012-07-28T20:00:04 --> 2012-07-29T02:05:04

A prominence erupts on the SW limb displaying rolling motions. During its slow rise phase, there is a flare/CME eruption in the nearby active region (~20:50) that shakes the prominence.
