This may present a border line between eruption and loop expansion. Dimming is clearly observed in association with the outward motion. However, no CME results from this action in the low corona.

The movie gives an impression that reconnection at low altitudes push matrial upward. The curved trajectory may imply that the jet traces closed field lines.

This surge may be of chromspheric to transition region temperature since it appers bright in 304 A and dark in 211 A images. Changes at the footpoint region do not appar to be very dynamic.

The prominence eruption is probably from the back side. It clearly fails to break into interplanetary space (no CME), which is partly understood by noticing that there is no dimming in the background structure. Unlike other well-known examples, this eruption is not reminiscent of kink instability.

2013-08-05T04:55:11 --> 2013-08-05T05:55:11
The jet itself is quite diffuse, but it can still be seen both on disk and over the limb. This event is characterized in dynamic changes at the footpoints, possibly with field line mixing.

2013-08-05T01:10:11 --> 2013-08-05T03:50:11
This erption appears to originate on the viisble side because we can identify both legs. The prominence is in the same line of sight as the cavity seen in 211 A images, but they seem to be not related. The eruption is so minor that there are no coronagraphic consequences.

2013-08-05T01:10:11 --> 2013-08-05T02:20:11
A minor eruption in the southern region seems to start as the material ejected in the norther region arrives. This seems to be a clear case of remote trigger of an eruption.

2013-08-04T22:10:11 --> 2013-08-04T23:50:11
The core part is seen to form, then to erupt between 22:52 UT and 22:54 UT, leaving a deep, although compact, dimming area. The white-light coronagraph manifestation is hardly a CME, which may be better called an outflow.

2013-08-04T14:30:35 --> 2013-08-04T16:00:35
Although the eruption itself is minor, it produces a ribbon-like emission at footpoints. Besides the eruption, the filament mateiral is seen to escape sideway to north. The associated small CME in LASCO data shows closed loops following a spiky structure.

2013-08-04T09:10:11 --> 2013-08-04T11:00:11
The eruption may be recognized only in the dimming above closed loops. No filament material is seen ejected. The even smaller eruption in northwest may not be related, since it is seen after this eruption over the limb.

2013-08-04T06:15:35 --> 2013-08-04T07:45:35
This may look like a failed eruption. The filament does not appear to escape. However, a CME is observed by LASCO, not very impressive but not too wimpy either. Difference images in 211 A /193 A indicate some minor dimming.

2013-08-04T05:20:23 --> 2013-08-04T06:50:23
A small prominence eruption followed by dimming in overlying structures. This is too minor to be observed later by LASCO. There is hardly a twist in the prominence and untwisting motion on the eruption.

2013-08-03T22:30:35 --> 2013-08-04T00:00:35
This is hard to recognize without inverting the color table or making difference images. The closed coronal structure is observed to reconfigure to let the jet travel to a larger distance.

2013-08-03T20:20:23 --> 2013-08-03T21:30:23
This ejection is the brightest in 304 A images. It is deflected northward, presumably reflecting the open field topology. The closed loops, most pronounced in 171 A images, are not affected presumably because they just happen to be in the same line of sight.

2013-08-03T17:30:35 --> 2013-08-03T18:30:35
A small prominence eruption is seen in 304 A images. This gives an impression of pushing surrounding open structrures aside as seen in 211 A and 171 A images. The event may be considered to be a jet, suggesting that jets and eruptions are similar after all.

2013-08-03T05:40:11 --> 2013-08-03T06:30:11
The footpoint seems to brighten to a B1.5 level. The jet is curved, probably tracing the coronal magnetic field lines.

2013-08-03T01:30:35 --> 2013-08-03T02:46:35
This is a diffuse jet, seen primarily in 211 A. It may appear reminiscent of the reconnection of a small bipole with adjecent open fields, as proposed by Shibata and co-workers in the 1990s.

Although the origin of this activity is TBD, it may reperesent at least part of the diffuse, slow and long-lasting outflow (and yet containing a flux-rope-like feature) in LASCO data. The prominence can be tracked in AIA data roughly between 03 UT and 08 UT, most notably in 171 A.

A series of surges propagate from the corona (overarching loops) off the W-limb. The source of the material is not obvious. The material appears to be pouring from 'thin air' and falling along the loop legs. Perhaps the material was previously cool (dark in 304), and behind the visible loops and heats up as it falls around the front of the loops, becoming visible.
