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 183 Issued at 2200Z on 01 Jul 2008IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 01-2100Z Solar activity was very low. No flares were observed
during the past 24 hours and the solar disk remains spotless. A
small, six degree filament near N53W40 disappeared sometime between
30/1811Z and 01/0542Z.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 30-2100Z to 01-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the first day (02 July). An increase to
quiet to unsettled is expected on the second day (03 July) and
predominantly unsettled conditions are expected to prevail on the
third day (04 July). The increase is expected because of a recurrent
high speed solar wind stream.
