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 2004  10CM FLUX: 095 / AP: 015
PREDICTIONS FOR 27 Jan 2004  10CM FLUX: 093 / AP: 017
PREDICTIONS FOR 28 Jan 2004  10CM FLUX: 103 / AP: 026
COMMENT: With a nearly spotless sun, we seem to be heading for a few days with
very littele activity on the sun. For the first 12 hours, some small (B- or
C-class) flaring activity may still be expected from the west limb, until the
active regions there have rotated away completely. Thereafter, the X-ray
background is expected to drop to A-level with no flares of significance.
Geomagnetic activity is currently quiet with a solar wind speed near 400 km/s
and decreasing. We expect quiet conditions for the rest of today and the first
half of tomorrow. During the second half of the UT day tomorrow, the Earth will
come under the influence of an equatorial coronal hole. We expect active
conditions from then onwards.
