2014-08-25T05:36:03 --> 2014-08-25T12:20:03
Filament activation in QS connected to a compact AR that later produces an ~M2 flare.

An ~M2 flare in a compact ARis associated with a large wave/propagating-front and a change in thermal/density structure connecting to a region towards the SE.

Eruption and fast propagation front (towards the NW).

2014-08-24T11:16:03 --> 2014-08-24T16:48:03
A mid-M clas flare near the E limb, associated with a large eruption, occurs synchronously with perturbations in a region halfway towards the W limb. Associated with the eruption from the E limb are oscillations in the high-coronal field. Shortly afterwards, a QS filament erupts from the S hemisphere, possibly in response to these preceding events.

Eruption from a fragmented AR and its surrounding QS, associated with a high-C class flare and a propagating front towards the NW.

The way the front propagates is very similar to the large-scale coronal propagating fronts on Aug 23 at 10 and 15 UT. This one was associated with a C6.0 flare. No type II burst reported, but there should be.

From AR 12146. Very similar to the previous event around 10:40 UT. Also associated with a decent CME (largely to west, but the northeastern quadrant includes a shock-like front) and type II burst.

From AR 12146. It was also associated with a type II burst and decent CME. Note that the front propagates past the west limb.

This started in AR 12148. It was associated with a type II burst.

AR 12146 is almost at disk center on Aug 22. It repeatedly sends out wave-like disturbances. This one is quite minor, with the front seen to propagate primarily in the west to northwest direction.

2014-08-20T11:40:11 --> 2014-08-20T14:30:11
There was a C4.9 flare at (12:38, 12:51, 12:56) at AR 12146. Although it showed a weak propagating front, a much clearer one occurred about an after the flare peak. Based on the GOES higher-energy (0.5-4 A) X-ray channel there was a small flare around this LCPF, and the background subtracted 1-8 A flux was about a B6 level.

a failed filament eruption results in a perfectly circular path being traced out by the uplifing material.

A filament near the west limb disappears in a puff. The activation involves matter moving horizontally before taking a sharp 90-degree turn upward.

Compared with the marginal eruption on the previous day, this seems to be a big event in the sense that the filament is clearly seen to erupt and traceable to a large distance. We also see spreading two-ribbon emission and dimming. We are predicting this to be Earth-affecting.

The prominence is seen to gradually rise and then to erupt. The impact to the adjacent corona seems to be negligible.
