SOLAR FLARES : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 20 Feb 2005 10CM FLUX: 095 / AP: 021

COMMENT: Low solar activity is expected. Only active region NOAA 735
keeps the potential for isolated C-flaring. Geomagnetic conditions are
expected to remain active under the influence of a high speed solar wind
stream and a possible arrival of the Feb 16 CME.
