SIDC SOLAR BULLETIN 20 Jan 2009, 1226UT
SIDC FORECAST (valid from 1230UT, 20 Jan 2009 until 22 Jan 2009)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 20 Jan 2009  10CM FLUX: 071 / AP: 006
PREDICTIONS FOR 21 Jan 2009  10CM FLUX: 071 / AP: 003
PREDICTIONS FOR 22 Jan 2009  10CM FLUX: 070 / AP: 003
COMMENT: Catania sunspot group 94, NOAA AR 1011, is unlikely to produce
a C-class flare. The Earth is currently inside the slow solar wind flow
(with the speed around 420 km/s) with weak interplanetary magnetic field
(around 2 nT). We expect quiet geomagnetic conditions.

TODAY'S ESTIMATED ISN  : 000, BASED ON 07 STATIONS.
