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 036 Issued at 2200Z on 05 Feb 2008IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next 3 days (06-08 February).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was at quiet levels. Solar wind speed at ACE
continues its downward trend with current values around 420 km/s.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at predominately quiet levels for the next two days
(06-07 February). Activity is expected to be unsettled on the third
day (08 February).
