SIDC SOLAR BULLETIN 20 Jan 2006, 1201UT
SIDC FORECAST (valid from 1230UT, 20 Jan 2006 until 22 Jan 2006)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 20 Jan 2006  10CM FLUX: 090 / AP: 004
PREDICTIONS FOR 21 Jan 2006  10CM FLUX: 089 / AP: 015
PREDICTIONS FOR 22 Jan 2006  10CM FLUX: 088 / AP: 012
COMMENT: Catania sunspot group 99 (NOAA AR 0848) is growing. However,
the magnetic polarities are clearly separated, so the flaring
probability is not very high. On the other hand, the decaying NOAA ARs
0847 and 0846 (they do not have sunspots and thus no Catania numbers)
still produce some activity (at the B-level) at the West limb. The
interplanetary conditions are not favorable for the development of
geomagnetic activity: the magnetic field is at the average level (5 nT)
and the north - south component Bz is oscillating near zero.

TODAY'S ESTIMATED ISN  : 017, BASED ON 02 STATIONS.
