Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 249 Issued at 2200Z on 06 Sep 2006

IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity was very low. New Region 909 (S08E25) was numbered today. Both Regions 907 (S13E31) and 909 have shown an increase in number of spots.

IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for an isolated C-flare from Regions 907 or 909.

IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field was mostly quiet. 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 mostly quiet.
