Small quiescent filament activation at southeast limb. The filament exhibits some rolling motion.

The eruption from AR 12320, associated with a C6.4 flare, involved an S-shaped structure. Its coronal response is well captured in 211 A images. Right after the passage of the front, the filament to the north of the active region started to erupt.

Small filament eruption from AR 12320. The appearance suggests the involvement of open field.

This can be easily overlooked, but a post-eruption arcade is seen to develop. Indeed, there was a slow but clear CME coming from the northern limb.

2015-04-12T09:00:03 --> 2015-04-12T10:00:03
This sequence gives an impression that magnetic field reconfiguration in AR 12320 leads to expansion of overlying field that smoothly becomes a slow CME, no dramatic energy release involved. Interestingly this occurred around the same time as the eruption in AR 12321 (in northeastern quadrant), which also exhibits similar phenomena.

The eruption was seen primarily southward, with an indication of rapid quasi-periodic oscillations (in difference images). The disturbance also went to the radial direction, also causing large-scale loops to oscillate.

This surge occurred in AR 12320 around the time of the short-duration C3.9 flare, associated with a marginal CME. Interestingly, a jet-like brightening is also seen around the same time in AR 12321.

This occurred in AR 12322. The associated CME was seen to deflect to a more radial direction.

The motions are largely along the filament. They are seen for many hours, possibly triggering a slow eruption.

The motions give an impression that they are clockwise They may signify a failed eruption, but the overlying structure (in 211 A imagtes) is disturbed, and a CME, although unimpressive, is observed.

Although mixed with returning material, this jet is best seen in 304 A images, presumably because it is dominated by cool plasma.

This eruption was associated with a C9.9 flare in AR 12320. The opening seems to nearrow, but a large area to the south of the active region was seen disturbed.

The eastern part of the long filament erupted, resulting in two-ribbion and post-eruption arcade emission that peaked at the GOES C3.8 level. In a later stage the eruption looked more like a big surge in 304 A iimages. The eruption seemed to activate the western part of the filament.
