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 090 Issued at 2200Z on 30 Mar 2008IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity was very low. The three spotted regions
on the disk continue to be stable and are generally declining.
IB. Solar Activity Forecast
Solar activity is expected to be
predominantly very low. There is, however, a chance for an isolated
C-class event during the next three days (31 March - 02 April).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was mostly quiet to unsettled during the past
24 hours. There was one isolated active period from 0000-0300Z. The
greater than 2 MeV electron flux at geosynchronous orbit was at high
levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled for the first day (31 March) and
should be generally quiet for the second and third days (01-02
April).
