2013-05-11T20:00:03 --> 2013-05-12T01:20:03
Mass flow (coronal rain) seen at 304 (cool) along transequatorial loops on the east limb.

2013-05-11T20:00:03 --> 2013-05-12T01:20:03
A large filament erupts near the northwest limb, drifting toward the west, producing a two-ribbon flare in its wake.

2013-05-18T07:36:03 --> 2013-05-18T16:02:03
A beautiful prominence eruption followed by a rather sophisticated pattern of coronal rain.

2013-05-18T01:04:03 --> 2013-05-18T02:16:03
A relatively small filament takes off on the E limb. What is peciliar is that most of kinking seems to happen at its apex.

2013-05-17T15:48:03 --> 2013-05-17T18:00:03
An eruption in the bottom right corner of the region of interese triggers a small wave in transequatorial loops to the S of it, which is soon followed by the field opening in the region in the top left corner of the region of interest.

2013-05-17T08:06:03 --> 2013-05-17T10:58:03
This movie shows an M-class flare, after which the eastern part of the filament (in the projection, roughly a third of its length) is gone and a bright arcade develops at the site of the flare. A massive coronal wave is triggered by this event (see my previous annotations). Yes, the western part of the filament (roughly 2/3rds in the plane of sky) do not seem to care. At all. The structure in the highlighted box does not change the shape _at_all_ in responce to all the changes around it and does not even _wiggle_ in the duration of this movie.

2013-05-17T08:06:03 --> 2013-05-17T10:58:03
An M-class flare resuted in a noticeable change in connectivity of AR loops. In particular, the arcade in the selected region of interest disappears and a coronal cavity is seen instead.

2013-05-17T08:06:03 --> 2013-05-17T10:58:03
This is a close-up into the source of the coronal wave which I annotated earlier. Pay attention to the Southern loop fan in 171A. After the flare has passed and the oscillations in the trans-AR loops have faded, there is an oscillation of intensity which shows up as a dark diagonal stripe progressing eastwards.

2013-05-17T08:06:03 --> 2013-05-17T10:58:03
This coronal wave extends to a good third of the entire limb and is visible in 211,171 and even somewhat in 304A.

2013-05-10T18:10:03 --> 2013-05-11T00:40:03
A giant prominence eruption like a huge plume of 1/2 R_sun across; the eruption velocity in the low corona is already >400 km/s. Much material falls back, lasting 6 hours after the initial eruption.

2013-05-10T00:00:03 --> 2013-05-11T05:00:03
A prominence rises and grows into a nearly vertical column (similar to the one described in Okamoto et al. 2010, http://adsabs.harvard.edu/abs/2010ApJ...719..583O), then erupts/disrupts and falls back to the Sun.

2013-05-20T00:00:03 --> 2013-05-20T06:40:03
Two coronal cavities wtih embedded prominences on the southeast limb.

2013-05-20T08:30:03 --> 2013-05-20T12:40:03
A series of flares one after another associated with global coronal waves: two smaller flares occur first within two neighboring active regions (ARs), then a larger, two-ribbon flare occurs in the eastern AR between the earlier two flares, followed by another smaller eruption in the western AR.

2013-05-20T00:00:03 --> 2013-05-20T11:20:03
An M 1.7 flare on the east limb, associated with a CME. Note some earlier gradual rise of overlying loops that precede the main eruption. Later during the event, cool 304 (red) material appears and shines the post-flare loops. In hot channels (131, 94), SADs appear above the flare arcade (see Sam Freeland's latest event page for more movies).

A small scale eruption on the southeast limb likely a small CME: with coronal portion seen at 211 (green) erupting together with a prominence core seen at 304 (red).

2013-05-20T00:00:03 --> 2013-05-20T07:20:03
Coronal rain seen in the 304 channel forms at the apex of loops and slides down the two legs.

2013-05-20T00:00:03 --> 2013-05-20T07:20:03
An active region prominence is lifted up and transported horizontally, the falls back down.

2013-05-20T00:00:03 --> 2013-05-20T19:00:03
An interesting prominence right at the north pole in projection. It must be located at a very high latitude to appear there.
