SIDC SOLAR BULLETIN 11 Jan 2010, 1220UT
SIDC FORECAST (valid from 1230UT, 11 Jan 2010 until 13 Jan 2010)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 11 Jan 2010  10CM FLUX: 087 / AP: 017
PREDICTIONS FOR 12 Jan 2010  10CM FLUX: 090 / AP: 013
PREDICTIONS FOR 13 Jan 2010  10CM FLUX: 091 / AP: 007
COMMENT: Solar activity is expected to be moderately active with risks
of C-class flares from NOAA AR 1040. Geomagnetic activity is expected to
be quiet to unsettled. A coronal hole is approaching geoeffective
longitudes and it might increase the geomagnetic activity to unsettled
levels either later on Jan. 11th or on Jan. 12th. Current readings of
the solar wind conditions as measured by the ACE spacecraft reveal an
increase in the solar wind speed and moderate excursion of the Bz
compoment of the interplanetary magnetic field, suggesting the Earth
might indeed enter the fast solar wind stream linked to this coronal
hole.
