2017-05-05T03:50:25 --> 2017-05-05T05:30:25
The pre-eruption filament is not clear, but the formation of flare ribbons and loops between them suggests an eruption. An area larger to the south more extended than the ribbons is seen to dim, especially in 171 A.

Continued surge-like activities came from two regions near the limb. It is not clear whether the eruptions only delineated closed structures, or how the two regions were linked.

The pre-eruption filament was not clearly seen, but a moving dark feature may have been a filament eruption. The event was captured only in 304 A channel, without showing clear flare ribbons or post eruption arcades

2017-05-01T12:55:13 --> 2017-05-01T13:50:25
This eruption was associated with a B3.0 flare from the same region (without NOAA AR number) as the earlier B9.9 flare. The eruption itself was weaker, but the coronal wave is clearly seen to propagate counterclockwise along the limb in difference images especially in 193 A channel.

The eruption associated with the B9.9 flare was pronounced in the radial direction. But difference images also show a large scale wave propagating counterclockwise along the limb.

This eruption came from the same region as the jet on 30 April 2017 18:30 as reported earlier. It now involved ejection of cool material, most of which seemed to fall back. It was associated with a short-duration B9.9 flare.

This jet is not clear close to the origin, although small post flare loops are seen indicating magnetic reconnection between closed and open field lines. It is easier to be seen at higher altitudes (within AIA FOV) as the surrounding structures being pushed away. Running difference images (not shown here) reveal an outward motion in intensity deficit (dimming) in all the three channels in the movie.

The eruption started slowly in AR 12653 (without a clear filament as a marker) but produced significant coronal dimming on both sides of the flare ribbons. Post eruption arcades were formed, explaining the associated B3.0 long-decay event in soft X-rays. This eruption did not arrive at Earth.

This may be a disk view of a failed eruption which does not escape from the Sun. It occurred in AR 12653, which had already decayed to 1/3 of its maximum size.

The eruption nicely shows helical motions that may indicate a flux rope. Some citizen scientists said that this was a breakout eruption, but it does not look that way. Reconnection signatures expected before and during the main eruption are weak. This may be more consistent with kink- or torus-unstable eruption. The eruption in the radial direction was obviously not smooth with disturbances slowly moving horizontally, especially counterclockwise. This is consistent with disappointingly small presence of the consequence of the eruption in LASCO data.

At low temperatures, this event looks like a mini filament (prominence) eruption, but in 211 A channel (especially in running difference images, not shown here) it is more like a jet. Perhaps another example to suggest the intimacy between these two phenomena.

One jet close to the limb was followed by another with clearer footpoint brightening. These may be nothing special, but they are more easily discernible than others.
