2015-12-03T05:45:34 --> 2015-12-03T07:31:34
Another flare from AR 12458. The associated eruption is mild, but it encompasses a large area, on the basis of the extension of the post-eruption arcade.

2015-12-02T23:20:22 --> 2015-12-03T01:50:22
A slow eruption from a region slightly behind the limb (AR 12457?). Dimming is seen higher up in the corona, but the eruption is compact, starting at lower altitudes.

2015-12-02T16:40:10 --> 2015-12-02T19:00:10
No disk signatures in AIA images. Images from EUVI on STEREO-A show the source location to be about 40 degrees behind the limb.

2015-12-02T04:20:22 --> 2015-12-02T05:30:22
Another C-class flare in AR 12458. Compared with the previous one on Dec 1 at 08:10 (C3.6), the eruptive signatures are significantly suppressed even though we see overlying coronal structures open up (producing minor dimming) and post-eruption arcades form. LASCO images show a diffuse outflow which can hardly be a CME.

This flare in AR 12458 accompanied fast-mode MHD waves, seen as a large-scale coronal propagating front (LCPF) both on disk and over the limb and narrow wave trains in the direction of 1 o'clock. Possibly because of the well-connected location, an electron event was observed by ACE/EPAM (but not protons).

2015-11-26T19:50:06 --> 2015-11-27T08:00:06
A minor eject of mass (darkening at 211 \\AA) was associated with a minor flare in the AR near the East limb, which was then followed by an active region filament eruption. Also note the proximity in time of another minor flare (annoted above) near the disk center.

A minor flare in AR near disk center, producing flare ribbons, and loop brightenings. It was initiated with some subtle eruption/ejection of mass.

2015-11-26T00:00:06 --> 2015-11-27T00:00:06
A sizable prominence on SW limb exhibiting quite a bit horizontal flows.

Dynamic flow patterns in a prominence on the east limb. Eventually prominence mass rains down along loop-like trajectories. Otherwise, the Sun has been fairly quiet over Thanksgiving

Much of the material in this confined/failed filament eruption seem to drain back toward the solar chromosphere. Bright loop footpoints at the western edge of the filament system are seen to light up as a consequence of mass drainage.

This filament eruption seems to lose steam before material is able to be ejected out of the Sun's gravitational well. Most of the filament material seems to disappear in-situ or or to drain down along loops.

The erupting material exhibits apparent unwinding motion.

It is hard to tracxe the origin of this eruption, which was not associated with a GOES X-ray flare. The formaiton of spreading flare ribbons and post-eruption arcades became clear only after 12:00 UT or so. Its location may provide interesting effects on its encouter with the Earth. Although no clear CME was found in LASCO data (not surprising given its modest extent), the erutpion could have been deflected by two coronal holes, small narrow one to the northeast and big coronal hole covering the south pole. We will see...
