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 030 Issued at 2200Z on 30 Jan 2008

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

Solar activity was very low. Region 982 (S09E40) has grown slightly in white light area coverage and has a magnetic beta configuration.
IB. Solar Activity Forecast
Solar activty is expected to be very low.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet for 31 January. Predominately unsettled with isolated active conditions are expected for 01-02 February due to the influence of a recurrent coronal hole high speed stream.
