2012-06-29T00:30:04 --> 2012-06-29T06:50:04
Filament (304, red) eruption near the SW limb leaves behind double flare ribbons and post-flare loops seen at 171 (yellow).

2012-06-29T17:15:04 --> 2012-06-29T18:15:04
A cornucopia-shaped surge occurs in an active region. It bumps onto those tran-equatorial loops and instigate their transverse oscillations. Note the beautiful ring at the leading edge of the surge.

2012-06-29T00:00:04 --> 2012-06-29T21:20:04
Recurrent surges from the active region accompany small flares almost every hour over the entire day. Also note the brightening/appearance of the large trans-equatorial loops at about 13:00 UT.

2012-06-29T00:00:04 --> 2012-06-29T21:20:04
A portion of the prominence on the NW limb gradually rises up, while shedding its mass (by drainage), and accelerates into a runaway eruption. In the late stage, there is very little prominence material (seen at 304, red) left in the rising structure, which is best seen at 171 (yellow) and exhibits unwinding twists as it erupts. Note that the eruption develops in a gradual (rather than impulsive) manner. This is probably a perfect example for the mass unloading mechanism of CME initiation proposed by B. C. Low (e.g., 2001, JGR, http://adsabs.harvard.edu/abs/2001JGR...10625141L). See a similar gradual eruption, but with no dramatic mass drainage, observed by R?gnier et al. (2011) at http://adsabs.harvard.edu/abs/2011A26A...533L...1R

2012-06-27T07:48:04 --> 2012-06-27T12:32:04
Coupled/synchronized filament eruptions from the W limb.

2012-06-27T14:44:04 --> 2012-06-27T16:56:04
AR surge of cool material being thrown upward as the field evolves, with a very compact flare at the base (with clear diffraction pattern).

2012-06-23T23:00:04 --> 2012-06-24T05:10:04
Eruption on the SW limb.

2012-06-25T05:50:04 --> 2012-06-25T12:40:04
Small prominence eruption on the NW limb.

2012-06-23T23:00:04 --> 2012-06-24T23:20:04
A prominence forms out of coronal condensation above the limb. Note the gradual increase of cloud-like emission at 171 (~0.8 MK) prior to the initial condensation at 304 (~0.08 MK). This is quite similar to another condensation event recently reported by Liu et al. (2012, ApJL), see http://adsabs.harvard.edu/abs/2012ApJ...745L..21L

An active region filament erupted just a bit behind the eastern limb.

2012-06-23T00:00:04 --> 2012-06-24T00:00:04
A C3 flare eruption from the AR on the NW limb appears to trigger a series of eruptions to the south. Could this be an example of sympathetic eruptions?

2012-06-23T06:00:04 --> 2012-06-23T08:50:04
Material rises underneath a prominence inside a coonal cavity on the NE limb, as a possible signature of flux emergence, similar to prominence bubbles discovered by Hinode.

A horseshoe-shaped filament erupted from the southern hemisphere on the disk, leaving behind double flare ribbons and post-flare loops.

A surge from a quiet Sun region (NE) on the disk displays untwisting motions as it unwraps itself. The sense of rotation seens to be counter clockwise when viewed from top down.
