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 129 Issued at 2200Z on 08 May 2008IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
Geomagnetic field activity was at mostly quiet levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
during the period.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet to unsettled levels on day 1 (09 May).
Activity is expected to decrease to quiet levels during days 2 - 3
(10 - 11 May).
