AR 12494 appeared suddenly late on 2016-02-02, followed by rapid growth into a delta configuration. Only C-class flares have occurred so far, but the region may produce stronger events.

The flux emergence seems to trigger the surrounding activities and an active region eruption nearby.

A series of activities (active region brightenings, filament eruptions) occur following a path from NE limb toward SW. The physical connections between these events are unclear.

Large-scale loop activity at East limb. The activity seems to relate to the filament eruption earlier to the NW.

2016-02-03T03:30:06 --> 2016-02-03T10:50:06
Quiet Sun filament eruptions. Two filament channels are involved. After eruption, the filaments still can be seen, which may indicates a partial eruption or a reformation process.

Dynamic flow patterns in the prominence within the coronal cavity on NE limb. At times, e.g., 15:00-17:00 UT, there appeared to be helical motions in the prominence material, going up and then back down.

Numerous surges from AR 12473 continued for another day. This had been happening throughout the disk passage of this interesting AR. The surges all originated from the western/leading sunspot.

A large surge, among many others of this day, from AR 12473. Note that aside from the surge shooting toward the limb (lower right hand), there's material flowing along the channel of the AR filament toward the lower-left hand direction.

Recurrent surges/jets from the leading (western) sunspot of AR 12473 continued with increasing activity level and sizes of the surge. Some involved activation and mass flow in the filament within the AR.

An interesting quadrupolar geometry in the transequatorial loop system on the east limb. The central part shows a clear dip in the overlying loops.

The large north-polar coronal hole now sits near the central meridian and occupies about 1/2 of the northern hemisphere.

Recurrent surges/jets from the leading sunspot in AR 12473 continue for another day. Note this sunspot is adjacent to a dark region to the west of it, most likely a local coronal hole, and the open field lines there may explain why this sunspot is so productive in spitting surges/jet.

A global coronal EUV wave propaged across the whole visible solar disk. Clear deflection/reflection occurred at the boundary of the southern polar coronal hole.

M1.9 flare occurred 11:20 on Dec 28, developed gradually to its EUV peak emission around 13:30 (GOES 1-8 /AA/ peak at 12:45, see http://www.lmsal.com/solarsoft/latest_events_archive/events_summary/2015/12/28/gev_20151228_1120/index.html). A coronal EUV wave was associated with the flare. Recurrent surges continue to originate from the leading sunspot of this AR (since a few days ago).
