SIDC SOLAR BULLETIN 18 Feb 2005, 1237UT
SIDC FORECAST (valid from 1230UT, 18 Feb 2005 until 20 Feb 2005)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 18 Feb 2005  10CM FLUX: 108 / AP: 025
PREDICTIONS FOR 19 Feb 2005  10CM FLUX: 105 / AP: 021
PREDICTIONS FOR 20 Feb 2005  10CM FLUX: 102 / AP: 022
COMMENT: A disturbance in the solar wind caused minor storm conditions
(K=5) last midnight. We expect the geomagnetic activity to remain K=3 to
4 because of an coronal hole influence in the northern hemisphere. By
the end of the weekend continued geomagnetic conditions are possible due
to the arrival of the full halo CME of 2005/02/17 (00h06).
