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 066 Issued at 2200Z on 06 Mar 2008IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity remains at very low levels. Region 984
(S08W80) is a small beta sunspot group rotating quietly around the
west limb. The rest of the solar disk and limb is very quiet.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit briefly exceeded high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to range from quiet to minor storm levels over the next
three days. Quiet to unsettled conditions are expected on 7 March. A
recurring high speed coronal hole stream will rotate into a
geoeffective position on 8 March, and produce occasional active to
minor storm periods on 8 and 9 March.
