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 091 Issued at 2200Z on 31 Mar 2008IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 31-2100Z Solar activity was very low. Region 988 (S07W35)
produced today's only B-class flare, a B2/Sf at 0534Z. All three
regions on the disk were quiet and stable and show an overall
declining trend.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 30-2100Z to 31-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was high during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days (01-03 April).
