SIDC SOLAR BULLETIN 21 Jan 2006, 1212UT
SIDC FORECAST (valid from 1230UT, 21 Jan 2006 until 23 Jan 2006)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 21 Jan 2006  10CM FLUX: 092 / AP: 011
PREDICTIONS FOR 22 Jan 2006  10CM FLUX: 094 / AP: 012
PREDICTIONS FOR 23 Jan 2006  10CM FLUX: 093 / AP: 016
COMMENT: Catania sunspot group 99, NOAA AR 0848, is continuing to grow
and to develop a more complicated configuration of the photospheric
magnetic field. We thus expect C-flares to occur in this group. An
equatorial coronal hole is now situated at the central meridian. We
expect the fast flow from it to arrive to the Earth around January
23-24, producing a geomagnetic disturbance up to the minor storm level.
The Earth is currently inside the slow solar wind flow with an average
magnetic field, so the probability for a geomagnetic disturbance in the
next 24 hours is low.

TODAY'S ESTIMATED ISN  : 019, BASED ON 01 STATION.
