SIDC SOLAR BULLETIN 26 Jan 2006, 1356UT
SIDC FORECAST (valid from 1230UT, 26 Jan 2006 until 28 Jan 2006)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 26 Jan 2006  10CM FLUX: 089 / AP: 016
PREDICTIONS FOR 27 Jan 2006  10CM FLUX: 087 / AP: 011
PREDICTIONS FOR 28 Jan 2006  10CM FLUX: 085 / AP: 007
COMMENT: Active region Catania#99 (NOAA0848) is decaying and has now a
simpler beta magnetic configuration. Therefore, we expect a low solar
activity with only a slight chance of C flare.
The geomagnetic activity rose temporarily to active levels in the last
few hours due to a new rise of the solar wind speed, associated with a
negative Bz, that was not expected. Now, the speed has stabilized at
550km/s, with the Bz component fluctuating between + and - 10 nT.
Although, the geomagnetic field is now back to unsettled levels, we
predict unsettled to active conditions for the next 24 hours, then
followed by a decay to quiet to unsettled conditions.

TODAY'S ESTIMATED ISN  : 016, BASED ON 01 STATION.
