SIDC SOLAR BULLETIN 31 Jan 2007, 1210UT
SIDC FORECAST (valid from 1230UT, 31 Jan 2007 until 02 Feb 2007)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 31 Jan 2007  10CM FLUX: 089 / AP: 011
PREDICTIONS FOR 01 Feb 2007  10CM FLUX: 090 / AP: 012
PREDICTIONS FOR 02 Feb 2007  10CM FLUX: 090 / AP: 010
COMMENT: The solar activity was very low during the last 24 hours, with
B-Class flares observed by the GOES instrument. It is expected that
quiet conditions will prevail, with a small chance of C-class flares
from NOAA AR 0940. NOAA AR 0941 has a very simple magnetic configuration
and should not give noticeable flaring activity.
The geomagnetic activity settled down during the last 24 hours. The
Earth is still in the high speed stream coming from the southern coronal
hole, with solar wind speeds of about 650km/s as measured by the ACE
spacecraft. Quiet conditions are expected for the next 48 hours with
some risk of isolated periods of unsettled conditions.
