2012-09-02T00:45:35 --> 2012-09-02T01:45:35

The eruption starts around 00:58 UT, when a small prominence moves to south first and then upward. The overlying structure contains both the frontal loop and the cavity as in the textbook.

2012-09-02T17:40:12 --> 2012-09-02T19:00:12

As the last one of the day in the series, the eruption is restricted to the northern part of the active region and there are hardly large-scale manifestations. Note that some dark material comes back to the surface.

2012-09-02T13:20:23 --> 2012-09-02T16:20:23

The event starts off as other examples in Series of minor eruptions (Eruption ), but this one has a consequence of getting a larger filament on the western side erupt. The filament eruption does not seem to have impact on large-scale loops hanging out on the limb as observed at 211 A.

Four or five areas brighten in this movie. Which ones have causal relations broadly speaking?

2012-09-02T01:30:00 --> 2012-09-02T02:32:00

This event is similar to previous examples in "Series of minor eruptions (Eruption )", but here the hot plasma observed in 94 A is emphasized. The flare itself seems to be not eruptive, but accompanies a westward ejection (along loop structures to an adjacent region) and an expansion of the eastern lobe of the sigmoid structure.

2012-09-01T23:30:35 --> 2012-09-02T00:20:35

Compared with previous events in the series this one seems to be more localized andless ejective.

Flare and eruption for a smallish AR, then a filament activation/eruption from a neighboring AR.

2012-09-01T20:00:07 --> 2012-09-01T20:40:07

It is not clear how to call this event, which is much clearer at 193 A than at other wavelengths. What is the driver for this?

2012-09-01T14:30:39 --> 2012-09-01T15:30:39

The ejection os clearer at higher altitudes. This may be a kind of streamer-puff CME.

2012-09-01T09:30:35 --> 2012-09-01T10:50:35

Apart from an apparent injection of mass (~09:55, dark in 193 A), it looks like the pre-existing open flux tubes are somehow excited by disturbances lower down.

2012-09-01T03:20:23 --> 2012-09-01T04:10:23

This looks quite fast. The origin is not clear unless further analysis is conducted.

2012-09-01T21:50:23 --> 2012-09-01T22:50:23

Similar to previous events, but dimming is less clear here, and the eastern part of the region shows more changes, perhaps in response to loops moving into the region.

Again a minor eruption in AR 11560.

Similar to the previous event. The eruption is primarily toward west.

AR 11560 now looks like a sigmoid. It shows minor, but repeated eruptions with a small transient dimming at 211 A (and 193 A).

This movie covers several hours after the spectacular filement eruption associated with a C8.4 flare. The remnant filament material shows interesting trajectories.
