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.

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 005 Issued at 2200Z on 05 Jan 2010

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

Solar activity was very low. Early observations indicated that Region 1039 (S29W90) remained a D-type sunspot group with a beta magnetic classification. However, later observations report the region as spotless as it rotates toward the west limb.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be predominantly quiet for the next three days (06-08 January).
