SIDC SOLAR BULLETIN 18 Jan 2012, 1224UT
SIDC FORECAST (valid from 1230UT, 18 Jan 2012 until 20 Jan 2012)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 18 Jan 2012  10CM FLUX: 140 / AP: 006
PREDICTIONS FOR 19 Jan 2012  10CM FLUX: 140 / AP: 003
PREDICTIONS FOR 20 Jan 2012  10CM FLUX: 139 / AP: 006
COMMENT: Catania sunspot groups 20 and 21 (NOAA ARs 1401 and 1402
respectively) have beta-gamma configuration of their photospheric
magnetic field. However, during the past 24 hours their configuration
somewhat stabilized, resulting only in five weak C-class flares. We
expect flaring activity at the C-level, with an M-class flare possible
but unlikely. Several large quiet Sun filaments are approaching the
solar central meridian. If any of them erupts, the resulting CME may be
directed at the Earth. The Earth is currently inside a slow (around 400
km/s) solar wind flow with average (around 5 nT) interplanetary magnetic
field magnitude. We expect quiet geomagnetic conditions.

TODAY'S ESTIMATED ISN  : 083, BASED ON 03 STATIONS.
