SIDC SOLAR BULLETIN 08 Jan 2012, 0835UT
SIDC FORECAST (valid from 1230UT, 08 Jan 2012 until 10 Jan 2012)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 08 Jan 2012  10CM FLUX: 142 / AP: 006
PREDICTIONS FOR 09 Jan 2012  10CM FLUX: 140 / AP: 021
PREDICTIONS FOR 10 Jan 2012  10CM FLUX: 138 / AP: 005
COMMENT: Solar activity is at eruptive levels and gradually increasing,
with the GOES X-ray flux background close to C level. More than seven C
flares were observed within the last 24 hours. Several more C flares are
expected within the next 24 hours, with a chance for an M flare,
especially from NOAA regions 11393 and 11388.
Solar wind velocities measured by ACE have been mainly between 420 and
460 km/s in the last 24 hours, with the IMF around 5 nT. Geomagnetic
conditions have been quiet in this period, and are expected to be
predominantly quiet on January 8 and 10. On January 9, a glancing blow
is possible from the CME first observed by COR2 A on January 5, 14:24
UT, in which case active geomagnetic levels are expected.

TODAY'S ESTIMATED ISN  : 065, BASED ON 04 STATIONS.
