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 279 Issued at 2200Z on 06 Oct 2007

IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z

Solar activity was very low. Newly numbered Region 972 (S05W06) emerged on the disk and is currently a small C-type sunspot group. It produced a B1 flare at 05/2307Z.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit remained at high levels today.
