Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 310 Issued at 2200Z on 06 Nov 2009 IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity was very low. Region 1030 (N24W07) was a simple beta group with 6 spots. No flares were observed. 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. IIB. Geophysical Activity Forecast: Solar activity is expected to be quiet on day one (07 November). Quiet to unsettled levels, with a slight chance for active conditions at high latitudes, are expected on day two (08 November) in response to a weak recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet levels on day three (09 November). III. Event Probabilities 07 Nov-09 Nov Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
