Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 251 Issued at 2200Z on 08 Sep 2006

IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was very low. Region 909 (S09W04) produced a long duration B5 event at 08/1058 UTC. LASCO imagery observed a faint halo CME, however, data was too scarce to be sure about the event. There were three low level B-class flares reported during the observed period, but no direct correlation can be made with the CME activity.

IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for an isolated C-class event from Region 909.

IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominately quiet. Quiet to unsettled conditions are possible for 11 September due to a recurrent coronal hole.

III. Event Probabilities 09 Sep-11 Sep Class M 05/05/05 Class X 01/01/01 Proton 01/01/01 PCAF green

IV. Penticton 10.7 cm Flux Observed 08 Sep 087 Predicted 09 Sep-11 Sep 085/085/085 90 Day Mean 08 Sep 077
