The >10 MeV proton flux hit 10 pfu. Is the C9.3 flare near disk center responsible? No It is the eruption from the farside (the detailed coordinates TBD because STEREO-A beacon data are still not available) that appears as a big CME.

An interesting eruption underneath a fan-spine dome that has been evolving for quite a few days. See a previous report for this structure at (http://www.lmsal.com/hek/her?cmd=view-voevent&ivorn=ivo://helio-informatics.org/TO171_WeiLiu_20131227_001305). The eruption takes place in two stages: first a lobe in the southern portion makes its way out and pushes the ambient corona; second the northern portion expands impulsively and opens up the dome, followed by reclosure of the field. There is not much noticeable flare emission. This mimics the scenario of sympathetic eruptions of the 2010/08/01 event that spans a greater spatial extent involving longer range connections, but the overall geometry could be similar. See observations by Schrijver & Title (2011, http://adsabs.harvard.edu/abs/2011JGRA..116.4108S) and simulations by Torok et al. (2011, http://adsabs.harvard.edu/abs/2011ApJ...739L..63T).

An eruption generates a coronal EUV wave propagating toward the south, and a two-ribbon flare.

2013-12-06T23:20:03 --> 2013-12-07T01:00:03
A small-scale eruption opens up some coronal volume and pushes nearby loops aside.

LASCO observed a bright halo CME at 2013/12/26 03:12 UT. The source region seems to be at approximately S10 E15 from STEREO-B, which is 151 degrees behind the Sun-Earth line. So AIA has recorded an eruption from 76 degrees behind the limb. No flare is associated, of course.

2013-12-05T23:00:03 --> 2013-12-07T00:00:03
Transequatorial loops between active regions in across the equator exhibit dynamic evolution, possibly evidencing on-going slip-running reconnection.

2013-12-06T18:40:03 --> 2013-12-06T19:30:03
AIA 171 images nicely show a fan-spine topology, with multiple closed loops underneath a helmet and spine-field lines opening to the high corona.

Some coronal mass (seen in the 171 channel) lifts off in the high latitude polar crown region above the northwest limb.

A coronal cavity and embedded prominence on the NE limb. Note the 171 horns surrounding the prominence material.

For a day or two, there has been no single active region on the visible northern hemisphere that are occupied by the quiet Sun regions and large-scale filament channels, although there is a string of ARs on the southern hemisphere. It is quite asymmetric

2013-12-04T20:00:03 --> 2013-12-05T03:00:03
A giant filament traversing almost the entire visible northern hemisphere erupted. Its eatern part went off first, producing a two-ribbon flare and bright arcade of flare loops. It's western portion followed, but most of the material fell back toward an anchoring footpoint to the west.

Some large-scale eruption, likely from the backside (no clear front side disk signatures), involved expansion and displacement of loops and possibly a surge seen in the 304 channel.

Episodic surge activity on the east limb from an active region displays a beautiful spray with an array of ballistic trajectories of material falling back to the Sun.
