SIDC SOLAR BULLETIN 19 Apr 2005, 1211UT
SIDC FORECAST (valid from 1230UT, 19 Apr 2005 until 21 Apr 2005)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 19 Apr 2005  10CM FLUX: 080 / AP: 011
PREDICTIONS FOR 20 Apr 2005  10CM FLUX: 079 / AP: 022
PREDICTIONS FOR 21 Apr 2005  10CM FLUX: 078 / AP: 016
COMMENT: Active geomagnetic conditions are possible from late this
evening since the small southern coronal hole is approaching a
geoeffective position. Flaring activity is low, the background
X-radiation is in the A-level. Sunspot group 52 is a possible candidate
for producing C-flares, but we expect mainly B-flares to happen.
