:Product: 20031009RSGA.txt :Issued: 2003 Oct 09 2200 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 282 Issued at 2200Z on 09 Oct 2003 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was at very low levels. The largest flare was an optically uncorrelated B8 at 1510Z. Region 471 (S08W44) decreased in area coverage and has simplified to a beta magnetic configuration. Region 478 (N10W06) was numbered today. IB. Solar Activity Forecast: Solar activity is expected to be at very low to low levels. Region 471 has the potential for C-class flares. IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet to unsettled levels with one period of isolated active conditions during local night time hours. IIB. Geophysical Activity Forecast: The geomanetic field is expected to be quiet to unsettled. III. Event Probabilities 10 Oct-12 Oct Class M 10/10/10 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
