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 188 Issued at 2200Z on 07 Jul 2007IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was low. New Region 963 (S09E83) rotated
into view today and produced several B-class flares as well as one
C-class flare at 1430Z. Region 961 (S08W86) was quiet and stable and
is rotating off the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low for the next three days (08-10 July).
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the past 24
hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next two days (08-09 July). An increase
to unsettled levels is expected sometime on the third day (10 July)
in response to a recurrent coronal hole.
