2012-03-12T11:40:04 --> 2012-03-12T17:20:04

A least three consecutive flares occurred in the neighboring active regions within several hours, producing two-ribbon like brightenings and likely small surges.

New flux emerges next to a small, unnumbered active region and later causes a mini-eruption to occur

2012-03-23T10:00:04 --> 2012-03-23T12:09:04

Eruption over SW limb, with subsequent coronal oscillations

Prominence eruption from QS region over NW limb.

2012-03-20T01:54:04 --> 2012-03-20T06:16:52

One small eruption appears to trigger another small eruption.

2012-03-19T00:00:04 --> 2012-03-19T05:00:04

A dynamic prominence, that involves a filament apparently untwisting and erupting

2012-03-25T10:55:04 --> 2012-03-25T20:10:04

Very compact, very bright EUV emission from AR 11442. Perhaps its a contrast effect with the surrounding coronal hole environment, but this small AR seems brighter in the EUV than many much larger ARs in recent memory. Does the compact magnetic topology lead to more efficient heating?

2012-03-25T10:35:04 --> 2012-03-25T18:50:04

Small, low-lying coronal cavity above quiescent prominence on SW Limb.

2012-03-25T10:35:04 --> 2012-03-25T18:50:04

Low-lying coronal cavity (semi-circular) over quiescent prominence on NE limb.

2012-03-25T14:20:04 --> 2012-03-26T02:21:40

Two of the large mid-latitude filaments near the East limb interact to cause multiple eruptions. Small coronal cavities are visible above the filaments on the East limb.

2012-03-25T00:00:04 --> 2012-03-25T06:00:04

Moderate filament eruption on SE limb. Western side of filament seems to release to cause a "sling shot" effect of the filament upwards and to the East. Twisting motion evident throughout the event.

2012-03-25T09:35:04 --> 2012-03-25T23:30:04

C1.2 flare in AR 11438. Brightest kernel is at 12:45 UT but large-scale topological effects do not occur until ~14:30 UT. The reason seems to be that the initial flare causes a filament expansion that only slowly grows/rises until it collides with overlying coronal loops to then initiate rapid reconnection and "two-ribbon" flaring.

2012-03-25T19:10:04 --> 2012-03-26T00:00:04

Emerging flux just below AR 11442 causes a rapid rearrangement of coronal loop structure accompanied by a small flare. The flare did not register in the GOES data. The emerging flux apppears to grow to the West and collide with an existing separatrix dome to trigger the rearrangement.

2012-03-25T00:00:04 --> 2012-03-25T04:35:04

C3.0 flare from AR 11442 near disk center. The magnetic topology of this active region is interesting and the flare spreads rapidly from the center to the periphery to "circle around" the Northern half of the AR.

Closeup of the UFO prominence eruption annotated earlier. See the expanding cusp at 211 (green) and falling material at 304 (red).

2012-03-11T07:40:00 --> 2012-03-11T09:30:00

A coronal cavity on the southwest limb exhibits clear swirling motions, sometimes suprisingly circular. This is indicative of helical magnetic field lines, as expected from a twisted flux rope.
