SIDC SOLAR BULLETIN 29 Apr 2006, 1221UT
SIDC FORECAST (valid from 1230UT, 29 Apr 2006 until 01 May 2006)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 29 Apr 2006  10CM FLUX: 101 / AP: 003
PREDICTIONS FOR 30 Apr 2006  10CM FLUX: 103 / AP: 008
PREDICTIONS FOR 01 May 2006  10CM FLUX: 105 / AP: 006
COMMENT: Catania sunspot group 31 (NOAA AR 0875) keeps its beta-gamma
configuration of the photospheric magnetic field. We expect C-flares
from this group, with a possibility for an isolated M-flare. The Earth
is currently inside the slow solar wind flow. Interplanetary magnetic
field magnitude is close to average (5 nT). We thus expect quiet
geomagnetic conditions.

TODAY'S ESTIMATED ISN  : 031, BASED ON 03 STATIONS.
