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 249 Issued at 2200Z on 06 Sep 2007

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

Solar activity was very low. No significant flares were observed during the last 24 hours.
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 to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to active, with minor storm periods possible at high latitudes on 7 September due to a recurrent coronal hole. Quiet to unsettled conditions will prevail on 8 September. Expect quiet conditions to return on 9 September.
