This eruption may not be explosive, but multple sets of post-eruption arcades are seen, reflectibg the magnetic structure of the active region complex.

This filament eruption gives an impression that it involved a counter-clockwise rotation, perhaps reflecting the helicity of the active region.

The C5.6 flare occurred in AR 12465. The coronal wave is seen to deflect to south as it hits another active region.

The prominence started to erupt before the C1.4 flare started in soft X-rays. The eruption was not very extended, but the overlying corona dimmed.

This is a quite powerful eruption causing adjacent loops to oscillate. The source region is ~20 degrees behind the limb as found by EUVI on STEREO-A (see https://twitter.com/halocme/status/673901884822806528).

2015-12-04T14:25:10 --> 2015-12-04T15:15:10

This is similar to the earlier event starting around 10:40 UT in such a way that the overlying corona is somewhat disturbed, which corresponds to a marginal CME in LASCO data. But unlike the earlier event, no contemporaneous activity is seen in a region close to the central meridian.

The flare occurred during the SWPC outage (no GOES X-ray data), but it was tagged as a C4.0 flare. AIA 131 A data are consistent with that. We can see supra-arcade downflows (SADs) above the hot loop top, as we sometimes experience in eruptive flares.

This jet seems to have occurred in the western periphery of AR 12459. The large-scale corona over the limb was also affected. Around the same time, another minor eruption was seen closer to the central meridian.

One of the series of flares in AR 12458, whose magnitudes were decreasing. This one is tagged as B7.5. It actually consists of two peaks, and the first (second) peak is associated with a minor eruption in the south (north). The first eruption looks like a failed eruption.

Initially, this appeared to come from AR 12463 barely on the visible side of the disk. However, the coronal structures associated with this active region was not affected. Therefore the eruptuon should have originate in a region slighly behind the region, and the candidate is AR 12464.

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.

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.

No disk signatures in AIA images. Images from EUVI on STEREO-A show the source location to be about 40 degrees behind the limb.

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.
