Bulletin

There were two M class flares early today (M5.6 at 04:24 UT and M4.9 at 04:58 UT) from NOAA AR 2257. No associated CME was observed. More M-flares can be expected and due to the position of this AR very close to the west limb, a proton event at Earth may occur. The other ARs visible on disk are not expected to produce more than C-class flaring. A partial halo CME originating from NOAA AR 2261 was seen appearing first in LASCO-C2 at 15:36 UT on January 12. It is a faint CME with speed around 1000 km/s, that could have an Earth directed component with a possible predicted arrival on January 14 around 19:00 UT. Geomagnetic conditions are quiet and expected to remain so until the eventual arrival of the partial halo CME from January 12.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 076, basierend auf 08 Stationen.
