A pair of North Hemisphere Active Regions (ARs) in close proximity. The ARs have their polarity orientation almost in parallel. Interesting connectivity arises in the corona - especially an "X-point"-like configuration of fieldilnes.

Flux emergence is seen in AR12635, a young active region. (It was not named at time of planning.)

Reconnection jet (inverse Y shaped) near leading spot of AR12635 (at the time of planning this AR was not named). Also occurs in similar place in previous raster.

An unusual eruption (filament?) seem from AR12630 as it goes around the limb. Seen in all SJIs, plenty of swirling motions, some of the plasma falls back down as coronal rain, other gets projected and hangs around looking like prominence material that falls back down (see following OBS, taken after eclipse).

A very minor eruption. Not clear how high the filament reached.

A small filament erupted showing rotation (in 171 A), and disturbed the overlying corona to oscillate. Part of the corona stayed dimmed for 30-40 minutes (but no obvious CME).

Curious about what AIA saw while IRIS recorded "Small hot loops (Other)". In an extended field of view and temporal range, we indeed see a microflare + jet (17:55-18:10), which would be easily overlooked while hunting for big eruptions.

A new region with sunspots emerged north of AR 12634, which no longer shows spots. This may be promoted to AR 12635. It initially produced a few C-class flares, but may have already stabilized.

A small filament erupted from a quiescent region. Interestingly, the eruption was nearly cosincident with the earuption from behind the northwest limb. This was perhaps by chance.

This must have been from the backside since no eruptive signatures were noted on the visible side. A narrow CME was associated with this eruption. See the SEEDS CME catalog at http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20170208.161208.w042.v0328.p297&frame=16&r.

Small hot loops in AR12634, perhaps a microflare?

This occurred in the northern part of AR 12632, separate from but maybe affected by the earlier eruption in the southern part. The LASCO movie http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20170207.100007.w035.v0346.p292&frame=13&r contains both eruptions.

2017-02-07T07:40:13 --> 2017-02-07T10:40:13
This eruption started with tumbling motions of low-lying prominences. LASCO data do not clearly reveal a flux rope in the outflow (see http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20170207.100007.w035.v0346.p292&frame=13&r), but it looks more like a CME than earlier events on Feb 5.

The footpoint brightening occurred nearly simultaneously with an ejeciton that looked like a jet. Quick-look at the photospheric magnetograms indicates that the footpoint corresponds to cancellation rather than emergence.

It is hard to find what triggered this (perhaps just as a result of active region evolution), but the corona above AR 12632 gradually dimmed, perhaps representing a small and slow eruption.

A filament is moving toward northwest. If this is an eruption, it is highly non-radial. But the motions are seen only in 304 A channel, and it is possible that nothing erupted.

Similar to the earlier event around 01 UT. Marginal LASCO presence.

This was probably from a region slightly behind the west limb. It was non-radial toward the equator and seen most prominently in 304 A images. The associated CME was also narrow (see http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20170205.012545.w006.v0293.p299&frame=3&r).

The onset of a jet-like (narrow angle) CME eruption. Before the onset, some background loops are seen to retract towards the North (North is up). The associated CME was of slow-to-intermediate speed (~450 km sec; see http://spaceweather.gmu.edu/seeds/mkmovie.php?cme=20170203.182407.w018.v0460.p306&frame=11&r)
