2013-07-29T22:10:03 --> 2013-07-30T00:35:03
A prominence appears to become kink-unstable. This leads to a rapid outward motion and then dissappearance of the prominence. The coronal loop structure surrounding the promenence dissappears as well, and a radial coronal cavity forms, with radial streamer-like structures moving north and south, away from the prominence's original position.

2013-07-29T07:30:03 --> 2013-07-29T10:45:03
Three rapid eruptive flare/surge events occur in three nearby areas, separated by 100-200 Mm. They each peak at around 8:45, 935, 10:00 UT. In this case there do not seem to be obvious visible commentions between the possibly sympathetic events, save for some faint loops and a possible filament channel connecting them.

2013-07-29T12:10:03 --> 2013-07-29T19:45:03
This event is very similar to both SOL2013-07-25T00:55:03L141C087 and SOL2013-07-26T20:00:03L138C083 A flare occurres in the region at the SE of the FOV. A coronal dimming and surge-like disturbance then propagate north-ward. Like the event on the 25th, the 304 emission appeared diffuse. The event on the 26th appeared much brighter. These three similar events along the same filament channel appear to indicate that the same unstable magnetic configuration was reformed after each occurrence.

2013-07-29T01:50:03 --> 2013-07-29T08:50:03
A swirling filament appears quiescent and dark in 304A, until an arcade of loops rapidly forms behind the E-limb, causing the filament material to flow along an overarching filament structure appearing bright in 304. Then both the original filament and the arcade recede and vanish.

2013-07-28T15:05:03 --> 2013-07-29T16:00:03
A series of sympathetic events occur within the AR complex including NOAA 11800 and 11805. A series of B and C-class events are among them. A number of filament surges and activations are also observed, which flow between the ARs. This is AR complex is discussed in the Max Millennium message for 29-Jul-2013: http://www.solarmonitor.org/motd_pop.php?date=20130729

2013-07-28T00:00:03 --> 2013-07-29T02:15:03
Filament material flows along a helical magnetic field structure visable off the N-E limb. This is likely connected to SOL2013-07-26T18:25:03L031C049 which showed a 'double-U' structure. It appears that the flux rope moves about, due to the material flowing along it- or vice versa. During the event, some of the meterial erupts and flows east away from the Sun.

2013-07-29T09:45:03 --> 2013-07-29T13:30:03
Over a very short time, large over-arching coronal loops appear to open and become radial. No filament or chromospheric material appears to be expelled. Is this a CME with no 'bite'?

2013-07-27T11:25:03 --> 2013-07-27T13:35:03
A flare occurs, followed by a surge that propagates, out, then southward, then loops back northward.

A peaked structure, appearing like two U structures side-by-side, ~100 Mm off limb in the N-E quadrant forms slowly, visible in the coronal channels, and then fades away. Prominence material interacts with the structure, outlining its form.

2013-07-26T09:05:03 --> 2013-07-26T13:00:03
A series of surge-like eruptions of chromospheric material into the corona occur from an AR at the east limb. The eruptions are directed northward (non-radial). Most of the material appears to drain back down the field lines, only to erupt again.

This event is very similar to SOL2013-07-25T00:55:03L141C087. On the 25th of july, 2013, a N-ward propagating disturbance moved along the same filament channel as this event and resulted in a coronal evacuation/dimming. This time a rapid, bright surge is visable along the filament channel. It appears that the same magnetic structure has reformed after the previous event, resulting in a repeat.

This movie shows how the horizontal structure becomes more visible at 171 A as it is lifted up in the process of a prominence eruption.

2013-07-25T22:30:03 --> 2013-07-26T16:00:03
A cavity forms off limb within a region of large over-lying loops. There is not an obvious trigger for the cavity formation. Well before the initiation, underlying chromospheric material suspended in the corona surges southward. This may have destabilised the hotter material in the overlying loops above.

2013-07-26T00:00:03 --> 2013-07-26T05:05:03
An AR on the west limb produced a surge of material with a northward trajectory. Material suspended in overarching loop structures is removed and expelled during the surge.

2013-07-25T00:55:03 --> 2013-07-25T07:45:03
A flare occurrs in the northern portion of the AR at the bottom of the FOV. A disturbance in the corona is observed to propagate from the flare site to the north-west. The coronal emission decreases as the disturbance moves. Subsequently, the emission is restored in the dimming region.

2013-07-24T22:00:03 --> 2013-07-26T00:10:03
A prominence erupts at the north-west limb. It appears to consist of two segments oriented radially to the limb, that twist about eachother in a helical pattern- like a DNA strand. The two strands twist more tightly about each other as the eruption continues. There appears to be a pinched region where the axis of the helix was by the end of the eruption. A coronal cavity or dimming region forms slowly to the west of the eruption afterward.

A filament partially erupts at the S-E limb. Most of the material falls back southward, and some northward, outlining the overarching magnetic field structure.

Filament on east limb activates first, followed by a liftoff that is enabled via reconnection. In this reconnectdion event, one can see the newly involved set of fieldlines [and current sheet?] lighting up. As this is happening, material from an active region about 50 or 60 degrees away on disk also reconnects, and produces a C3 flare in the process. There is a lot going on here, and this movie doesn't do it justice.
