:Product: 20010607RSGA.txt :Issued: 2001 Jun 07 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 158 Issued at 2200Z on 07 Jun 2001 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was low. Isolated, mostly minor C-class events occurred during the period. The largest event was an impulsive, optically uncorrelated C6 flare that occurred at 07/2007 UTC. Most of the day's activity came from Regions 9484 (S06W47), 9488 (S18E04), and 9492 (N19E50). Region 9488 remains the most magnetically complex region with a beta-gamma magnetic classification. The rest of the disk and limbs were mostly quiet and stable. IB. Solar Activity Forecast: Solar activity is expected to be mostly low. A slight chance of isolated M-class is possible. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was at quiet to mostly unsettled conditions. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled conditions. III.
