Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

SDF Number 033 Issued at 2200Z on 02 Feb 2010IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was very low. No flares were observed
within the last 24 hours. Region 1041 rotated off the sun within the
last 24 hours. Region 1043 (N25W05) decayed to an alpha
classification. There was a CME observed off the west limb at
01/1945Z.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low with only a slight chance for a C-class flare.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet.
