The wave was seen mostly in northwest. It did not fully develop because of the presence of active regions (south to southwest) and a coronal hole (northwest). The deflected front gives an impression of a rotation counterclockwise.

2015-10-21T16:30:34 --> 2015-10-21T20:00:34

The flare took place to the southwest of the preceding spot of AR 12436, immediately following some motions in the filament encompassing AR 12437 (southeast). During the flare trans-equatorial loops between 12436 and 12435/7, and between 12436 and 12434, disappeared probably suggesting eruptions even though no clear filaments were seen.

2015-10-20T16:00:06 --> 2015-10-20T23:00:06

Gradual rising motions started around 16 UT, followed by what looked like an eruption. This was hard to confirm partly because of a data gap due to AIA weekly calibration. Post-eruption flare ribbons and arcades are essentially missing, so this may not have been an eruption.

AR 12434 occasionally shows activity on the active region scale. An example is these dynamic motions in two filaments that lie in the northwestern and southeastern sides of the region, which now looks like a sigmoid. So far no major eruptions, but we may need to monitor it for some time.

2015-10-19T18:10:10 --> 2015-10-19T19:20:10

This is the second day in which AR 12434 is classified as a BETA-GAMMA-DELTA. The spot area got a little smaller (260 --> 220 msh). There are multiple areas, small or filament-like, which brighten during this 70 min interval, but nothing leads to a major event. Hence a disappointing region. A minor eruption is seen close to the west limb , which may or may not be related to the minor activity in AR 12434.

2015-10-18T21:30:34 --> 2015-10-19T02:30:34

Nice prominence eruption with usual helical motions, following a slow rise. Interestingly the surrounding corona does not seem to be impacted as noted in 211 A/171 A images. Base difference images indicate that dimmint only slowly built up during the eruption. The associated CME contained flux rope like internal structures.

Thie active region looked quite dynamic, producing short-lived peaks (C-class flares) in the GOES X-ray light curve. But they seemed to be low-lying and did not affect the overlying structures.

A circular structure reminiscent of a flux rope was seen to rise, then to deflect into a narrow channel that looked like a jet. The adjacent corona on the northern side was seen to be pusehed aside during the ejection.

Three flares (M1.1, M1.5, and C4.7) flares occurred in AR 12437 in a 90 minute interval. Only the third one, the least intense in X-rays, seemed to be somewhat eruptive, causing the tall loops to oscillate.

Basically a non-eruptive flare as have been most of them this past week, this at least looked dynamic, disturbing the adjacent corona, probably by waves.

AR 12434 showed a big growth between 16 Oct and 17 Oct (the spot area from 50 msh to 150 msh). It got promoted from BETA-GAMMA to BETA-GAMMA-DELTA on 18 Oct. However, no major or eruptive flares were seen except that the filament that encompassed the region got activated or illuminated by discrete flares. But even this has ceased. The region may be similar to somebody who got inactive after getting a permanent position.

Starting from a backside flare with a narrow but powerful ejection, there were four flares within a 70 minute interval from different regions. Perhaps this suggests a possible linkage among these regions. See https://twitter.com/halocme/status/655193082283950080.

The first M-class flare in AR 12434. Apart from illuminating an adjecent area, the flare was essentially confined.

This event occurred in a quiescent region. It appeared in depression in 304 A image.
