Another limb eruption occured at the same location as the small limb eruption reported on Jan 21. Again the "X-point" structure is shown during the evolution.

Filament eruption NE of AR12488. The eruption seems to cause activities at NE limb.

2016-01-21T08:00:06 --> 2016-01-21T20:10:06
The sympathetic activities start from a small eruption near AR 12487, followed by a larger eruption in AR 12487. Several activities were observed thereafter involving AR 12488 and 12486.

A small eruption near the west limb. an "X-point" structure is shown before the eruption.

2016-01-20T00:00:06 --> 2016-01-20T17:50:06
Filaments activation near NW limb. Several filaments are involved. The activation leads to a filament eruption at around 17 UT.

2016-01-19T00:00:06 --> 2016-01-19T09:20:06
Quiet sun filament eruption. The eruption also causes synchronous activity of another filament to the north.

Cldearly there was an eruption on the back side, but it did not make it to coronagraph heights.

2016-01-16T17:00:06 --> 2016-01-17T06:00:06
Downflow of cool matrial (as seen in 304 A images) was seen for long time. It traces the lower (closed) part of the coronal structure as seen in 171 A images.

I occasionally start my annotations from looking at LASCO data for CMEs, followed by an attempt to find where the CME comes from. In this case, see http://cdaw.gsfc.nasa.gov/movie/make_javamovie.php?img1=lasc2rdf&img2=goesx&stime=20160116_0600&etime=20160116_1030. STEREO EUVI data suggest that the origin was not on the backside. There was no clear filament eruption on the visible side. Expanding loops limbward of AR 12485 seem to be the only possibility to account for the CME. We see mild dimming above the active region, which may have been connected to a larger area than what it looked.

This is associated with a C1.1 flare in AR 12480. Most of the ejected material seems to come back. The overlying corona is hardly impacted.

This jet-like eruption is most clearly seen in 304 A images. It appears that a straight, horizontal trajectory exists in addition to the one that falls down.

Without signs of footpoint brightening, the source region of this eruption should be occulted. The eruption seems to consist of a flux rope, which is consistent with the appearnace of the associated narrow but bright CME.

Minor eruption from AR 12480, triggering loops outside the AR to oscillate. A C2.8 flare was associated.

This is a slow filament eruption in a quiescent region and is seen to move in various directions in 304 A images. It has no X-ray flare signals, although a two-ribbon flare, spreading in time, is clearly seen in these images. At both ends of the ribbon, a twin dimming develops. This was predicted to be an Earth-directed eruption (https://twitter.com/halocme/status/687798333130338305), and the CME-associated shock indeed arrived late on January 18 (https://twitter.com/halocme/status/689198036434685952).
