2012-04-02T00:30:04 --> 2012-04-03T20:30:04

Magnetic field lines from AR 11143 (in the northern hemisphere) appear to be sucked into a coronal null point or spine. Apart from intermittent coronal jets, this type of reconnection results in magnetic lopos that straddle the equator. This is a candidate for direct observational evidence of cross-equatorial magnetic reconnection taking plane in the corona.

2012-03-31T20:30:04 --> 2012-03-31T23:30:04

This giant of a surge seems to be triggered by some reconnection event, which impulsively accelerates material up pre-existing open (far-reaching) field lines before much of the material falls back down.

2012-03-30T22:30:04 --> 2012-03-31T07:00:04

The northeastern portion of this quiescent filament erupts. Some material is seen to flow back down toward the remaining anchored portion of the original filament.

2012-03-30T11:38:04 --> 2012-03-30T19:20:04

One end of a large filament appears to lift up, swirl around, making a cone-like shape in the plane of the sky, and seemingly reconnects to some other part on the disk.

2012-03-29T23:04:04 --> 2012-03-30T05:32:04

Large filament close to the N pole becomes activated, slowly lifts up and seemingly breaks into two halves, which sink back into the surface.

2012-03-29T22:00:04 --> 2012-03-30T00:56:04

A small flux rope erupted from an anemone close to the W limb followed by a spray surge.

2012-03-29T08:34:04 --> 2012-03-29T13:48:04

A nice small eruption in the diffuse field followed by a prominent post-eruption arcade.

2012-03-29T14:56:04 --> 2012-03-29T22:20:04

A large filament in the N heisphere slowly takes off northwards. Some of the plasma in it could be seen in 171A flowing down the footpoints of the flux rope. Right after the eruption, a compact bundle of loops brighten up, that might belong to the post-eruption arcade. Given the length of this filament, the arcade is probably long too; why one small bundle in the middle of it brightens up and th rest does not?

2012-04-03T00:00:04 --> 2012-04-03T14:40:04

Moderate sized coronal cavity, fully elevated (not partially submerged into or obscured by the limb), and fairly elongated. Noteworthy for the very visible and "active" 171 flow into the cavity from the prominence below. The flow appears to be upward along "horns" but more extensive image analysis is required to confirm this.

2012-04-03T00:00:04 --> 2012-04-03T14:40:04

Fully elevated, elliptical cavity on SE limb. Associated prominence is moderate to small in size and reaches only to the bottom of the cavity.

2012-03-29T09:24:04 --> 2012-03-29T10:40:04

A spray surge is thrown upward by a flare. When it seemingly gets disconnected from the photosphere, a second flare takes place in about the same location on the limb. Then the first blob completely disappears in 60 seconds and as it happens, a second blob appears pointed in a slightly different direction and slightly offset but at about the same height. It is unclear at first sight whether it is an extremely fast transverse motion or an extremely fast decay and appearance of the second surge.

2012-03-28T16:24:04 --> 2012-03-28T22:50:04

An eruption produces coronal dimming in the field surrounding an AR. The "boundary" between AR emission and external field becomes clearly visible. The dimming lasts for a relatively long time.

2012-03-28T01:52:04 --> 2012-03-28T05:58:04

A prominence lifts up and falls back down as coronal rain. What makes it interesting is how there seem to be many U-shaped coronal loops "sitting" along the spine of the prominence and moving as it moves. The tips of the "U"s seem to be going upwards and out of the field of view.

Moderate filament activation from AR 11445, West of main sunspot. Small two-ribbon flare accompanies the activation.

2012-03-27T23:35:04 --> 2012-03-28T04:00:04

Moderate/Large eruption from behind East limb. Undoubtedly a CME but the Annonator widget for reporting CMEs is too complex to use so it is reported here only as an "eruption".

2012-03-27T20:30:04 --> 2012-03-28T04:00:04

Activation of filament causes counterstreaming from southerly section northwards (and back). This is probably flow along the same filament channel inclined in a SW-NE direction, not flow between two isolated filament sections. A similar large northern hemisphere filament is on the disk at the same time. Note the moderate/large eruption/CME just behind the disk at the same latitude.

2012-03-27T03:20:04 --> 2012-03-27T06:20:04

Filament eruption from compact, very EUV bright, AR 11442. The eruption is preceded by large-scale topological rearrangement that appears to propagate around the dome-like AR to finally expel material to the West. Note the nteresting "prarie fire" flare that expands and then contracts just prior to the eruption.

Prominence at West limb activates and then drains rapidly away via coronal rain into neighboring loop systems.
