A prominence forms at the N limb. A visually small fraction of it then gets ejected, while the rest falls back on the surface as coronal rain.

2014-01-18T05:00:03 --> 2014-01-18T22:00:03
Prominence material is observed to flow from one place to another. Simultaneously, a coronal cavity [as evident from the curved lower boundary evident in the ramped-up 171 channel] is observed to lift off. These dynamics do not appear to be associated with any explosive event; rather it appears to be more of a slowly evolving ejection that is proceeds via the gradual expansion of coronal plasma.

Filament on southwest limb activates. Some material is observed to stream down toward photosphere. It is unclear whether material was also ejected upward.

2013-12-25T16:30:35 --> 2013-12-25T18:00:35
Following a small-scale eruption, larger-scale loops are pushed sideways. This seems to correspond to an unimpressive CME observed at 18:00 UT.

As the prominence erupts, it appears to deflect southward. The prominence itself seems to have complex internal structures.

This is again searched from CME observations. The source region could be far behind the limb.

Because of a LASCO CME, we know something occurred around the position angle of 240 degrees (measured counterclockwise from the north pole). In this case the eruption was clearly on the far side. The most apparent signature is oscillations of coronal structures.

This prominence eruption suggests the presence of helical structures at both high and low altitudes. The associated CME was narrow but of flux-rope type.

This seems to be a prominence close to the north pole, indicating the presence of mixed polarity. No corresponding signatures are found in lower latitude regions.

This flare is again characterized by the surge-like ejection, dark in 211 A and 171 A. It was immediately followed by a M-class flare somewhere else, and not registered as a separate event. A bright CME was associated, which started narrow but later became extended.

This C6.1 flare is characterized by fast collimated ejections. A narrow (not flux-rope type) CME was already observed by LASCO at 19:48 UT.
