NOAA SEC Report of Solar-Geophysical Activity 8 June 2001
:Product: Report of Solar-Geophysical Activity :Issued: 2001 Jun 08 2200 UT # 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 159 Issued at 2200Z on 08 Jun 2001 IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was moderate due to a single M-class event, an M1/Sf flare from newly numbered Region 9494 (S08W30) at 08/1927 UTC. This region was numbered early today and has already developed into an 11 spot Dao spot group with a beta-gamma magnetic classification. Region 9494 also produced a C7/Sf flare at 08/1603 UTC. Another event of significance was a C6/1n flare with an accompanying Type II radio sweep (est. velocity of 600 km/s) at 08/0228 UTC. The rest of the disk and limbs were mostly quiet and stable. Region 9495 (N04E24) was also numbered today. IB. Solar Activity Forecast: Solar activity is expected to be mostly low. Region 9454 is capable of producing isolated M-class events during the forecast period. IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic filed was at mostly quiet to unsettled conditions. IIB. Geophysical Activity Forecast: The geomagnetic filed is expected to be quiet to unsettled. III. Event Probabilities 09 Jun-11 Jun Class M 30/30/30 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
