SIDC SOLAR BULLETIN 09 Apr 2005, 1217UT
SIDC FORECAST (valid from 1230UT, 09 Apr 2005 until 11 Apr 2005)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Minor geomagnetic storm expected (A>=30 or K=5)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 09 Apr 2005  10CM FLUX: 088 / AP: 005
PREDICTIONS FOR 10 Apr 2005  10CM FLUX: 087 / AP: 008
PREDICTIONS FOR 11 Apr 2005  10CM FLUX: 085 / AP: 026
COMMENT: Newly emerged NOAA AR 0751, Catania sunspot group 52, is
growing very rapidly. We do not exclude the possibility of a C-flare
from this active region. The Earth is still inside the slow solar wind
flow, and the geomagnetic conditions are currently quiet. However, a
large low-latitude coronal hole is visible in the northern hemisphere.
We expect the fast flow produced by this coronal hole to arrive around
April 11. Disturbed geomagnetic conditions up to the minor storm level
(Kp = 5) are possible.
