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 122 Issued at 2200Z on 02 May 2007IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was very low. Region 953 (S10W17)
produced several B-class flares during the past 24 hours. The
largest was a B8 at 02/1602Z. This region is currently classified
as a beta magnetic spot group. Region 954 (S06E01) also produced a
few low level B-class flares.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low with a slight chance for an isolated M-class flare.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit remained at high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominantly quiet for the next three days.
