Bulletin

Majority of the flaring activity during last 24 hours originated from the NOAA ARs 2470 and 2469 which just rotated from the behind of the East solar limb. The strongest, out of 6 C-class flares, was the C7.8 flare (peaking at 13:46 UT on December 12), which originated from the NOAA AR 2470, at that moment situated at the East solar limb. The flare was associated with rather narrow CME. The C5.3 flare (peaking at 10:34 UT today) originated from the NOAA AR 2468 which was at that moment situated rather close to the solar disc center. The flare was associated with the EIT wave, the coronal dimming and possibly Earth directed CME. More will be reported as soon as coronagraph data become available.

The solar wind speed is currently 490 km/s and the interplanetary magnetic field magnitude is about 4 nT. The fast flow from the narrow elongated low latitude coronal hole (between N8 and N30), which reached central meridian late on December 11, might arrive at the Earth in the morning of December 15. The geomagnetic conditions are quiet to unsettled and we expect it to remain so in the coming hours.
