Horizontal prominence threads, likely an active region prominence, as seen by Hinode/SOT by Okomato (2007 Sci), displays dynamic flows and wavy motions (Alfven waves?).

A prominence embedded in a coronal cavity has an unusual spine extending to the high corona. The spine is clearly seen at 171 with scattered 304 (cool) material along it. It is not clear what the physical nature of this off-limb spine is and what is its relationship to on-disk filament spines in Sara Martin's H-alpha observations.

An AR filament erupted from the newly formed active region from flux emergence yesterday, resulting in post-flare loops.

A new bipolar region emerges within hours and grows in size. At the same time, new connection with the vicinity in the form of various new coronal loops is being established, as seen at 171 in yellow.

A moderate-sized prominence on SE limb is rotating to the front side of the disk. It shows several episodes of activity, with rising volume of mass intruding from below, like the Tom Berger type of prominence bubbles or plumes. The cool 304 (~80,000 K) prominence is surrounded by relatively warm 171 (~0.8 MK) material, likely indicating the so-called prominence-corona transition region (PCTR).

A coronal cavity seen at 211 appeared on the NE limb, with a prominence embedded in the middle.

A small-scale active region filament was activated, but the eruption was confine to the local volume.

Cusp-shaped post-flare loops form after a possible small/weak filament eruption in the quiet Sun region.

2012-06-19T23:00:04 --> 2012-06-20T17:50:04
Cool 304 (80,000 K) material condenses out of the low corona at the lowest portion of funnel-shaped loops seen at 171. The condensation forms transient coronal rain on loops or a small-scale filament-like structure.

The eruption is seen between 00:40 and 01:00 UT. It is diffuse and seen primarily at 193 A (marginal at 211 A although differrence images show it more clearly). The prominence ~20 degrees east of the eruption seems to be unaffected.

Material is seen fall back to the surface. The magnitude appears to be correlated with upflows from the encircled area.

Two flares at C2.4 and B8.8 are captured in this movie. The first one corresponds to a jet (and strong DH type III burst observed by Wind WAVES). The second one appears as long post-flare loops, but it is not clear whether any eruptions preceded it. Note another jet-producing region just to the north of the first flare.

The eruption occurred around the time of a C3.4 flare, but they seem to be unrelated, since the latter is reported to be near disk center. The source region of this eruption is thus behind the limb. At 211 A, the front is seen, and at 304 A, the ejecting filament material is seen. The internal structure of the CME as seen in LASCO C2 data may correspond to the latter.

These jets appear to emanate from the southeastern penumbra of a spot. None of them hardly reached the STEREO COR1 field of view.

In the 304/211/171 combo movie, the eruption is most readily seen at 211 A, up to 13:40 UT or so, still in the rise phase of the associated M1.9 slow flare. Perhaps the main body of the CME started at higher altitudes.

A bright point in 211A above an ethemeral dipole is literally cracked into two halves by a persistent dark wiggling feature. A possible explanation is that this is an absorbing feature which resides above this region.

A nice sigmoid in an ethemeral region. The left footpoint has a clear swirling structure.

Two spray surges shoot upwards on the W limb. The one in the highlighted region demonstrates a peculiar evolution. It starts as a single structure somewhat resembling a portion of a slinkie which makes one full turn. Later on something happens in the bent part; the end of the slinkie which touches the surface connects to another location on the surface forming a shrinking loop, while the "open" end of the slinkie shoots radially upwards and - barely visible - downwards. It is the latter which makes me think the whole system was not just the line-of-sight overlap of a spray surge and a loop; the "open" end is clearly disconnected from the surface directly "below" it (as appears in the plane of sky) and gets connected in its latter stage of evolution.
