SIDC FORECAST (valid from 1230UT, 27 Nov 2004 until 29 Nov 2004)
SOLAR FLARES : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 27 Nov 2004 10CM FLUX: 113 / AP: 008
PREDICTIONS FOR 28 Nov 2004 10CM FLUX: 115 / AP: 007

COMMENT: Solar activity was quiet yesterday (26/11). Regions Catania 77 and 78
(NOAA 0707 and 0706) however started to show some activity again today. They
also have grown in area and magnetic complexity. From these regions and from new
region NOAA 0708 we expect more flaring activity. Geomagnetic conditions are
quiet. The solar wind speed is at present 440 km/s and Bz is fluctuating around
0. The coronal hole in the middle now of the disk, could become geoeffective
from 30/10 onwards.
