SIDC SOLAR BULLETIN 28 Jan 2010, 1326UT
SIDC FORECAST (valid from 1230UT, 28 Jan 2010 until 30 Jan 2010)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 28 Jan 2010  10CM FLUX: 078 / AP: 005
PREDICTIONS FOR 29 Jan 2010  10CM FLUX: 077 / AP: 003
PREDICTIONS FOR 30 Jan 2010  10CM FLUX: 076 / AP: 003
COMMENT: The only sunspot group on the solar disk (Catania number 37,
NOAA AR 1041) is decaying. An isolated C-flare is possible but unlikely.
The Earth is currently inside the slow (around 360 km/s) solar wind flow
with average (5-6 nT) interplanetary magnetic field magnitude. The
geomagnetic activity is expected to remain on the quiet level.

TODAY'S ESTIMATED ISN  : 008, BASED ON 05 STATIONS.
