SIDC SOLAR BULLETIN 31 Mar 2010, 1212UT
SIDC FORECAST (valid from 1230UT, 31 Mar 2010 until 02 Apr 2010)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 31 Mar 2010  10CM FLUX: 083 / AP: 005
PREDICTIONS FOR 01 Apr 2010  10CM FLUX: 082 / AP: 003

COMMENT: Catania sunspot group 54 (NOAA AR 1057) is continuing to decay
further. A C-flare is unlikely to occur in this group. The Earth is
currently inside the slow (around 420 km/s) solar wind flow with average
(4-5 nT) interplanetary magnetic field magnitude. We expect quiet
geomagnetic conditions.

TODAY'S ESTIMATED ISN  : 019, BASED ON 11 STATIONS.
