2012-08-28T00:48:03 --> 2012-08-28T08:20:03
Flux emergence next to (and trailing) a weak, decayed AR leads to the eruption of a small filament. The associated coronal front propagates at least to northward of the northern polar crown filament. Subsequently, a larger eruption occurs in the remains of the AR.

2012-08-27T08:40:03 --> 2012-08-27T11:50:03
A loop-shaped prominence (304, red) erupted on the SW limb, exhibiting unwinding twists; this is immediately followed by another eruption nearby seen at 211 (pale blue).

A small scale condensation of cool 304 material constantly drains mass, in a so-called "cloud prominence" (Tandberg-Hanssen 1995; S. Martin) configuration, see Liu, Berger, Low (2012, http://adsabs.harvard.edu/abs/2012ApJ...745L..21L) and references there-in; this could be similar to coronal rain in loops (see e.g., Antolin et al. 2012; http://adsabs.harvard.edu/doi/10.1007/s11207-012-9979-7).

A loop-shaped prominence eruption on SW limb, likely from the far side of the visible disk.

A very long, transequatorial filament channel runs across about 3/4 of the solar disk from north-east to south-west.

A close-up view on the site of the filament eruption. Despite quite spectacular foorpoint brightening, little of the flux rope is seen erupting until the later stages when it takes off from the field of view (dark feature travelling towards the top left corner).

The filament itself is not visible well until the last stages of the eruption, hovewer, the post-eruption brightening is quite spectacular in all channels.

Spray surges seem to be repetitively happening in the same location. What is going on there?

A coronal dimming is associated with a post-flare arcade and arcade signature in 304A, however there is no evidence of an erupting filament.

The overlying structure which shows in 304 (but not in 211 or 171) is suggestive of that the erupting structure is much thicker than the filament itself, and that the filament resides at its bottom. The cavity does not appear like a sphere, more like a thicker "shell" around the erupting flux rope. It is an interesting observation as I do not recall observing the signature of the top of the cavity that clearly in 304A and not in other channels.
