:Product: Report of Solar-Geophysical Activity :Issued: 2009 Jun 03 2201 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 154 Issued at 2200Z on 03 Jun 2009 IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity was very low. Three low-level B-class flares occurred during the past 24 hours. Region 1019 (N26E03) continues to have a few sunspots, but is a simple B-type group and was stable and quiet during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the first day (4 June) due to possible effects from recurrent activity. Conditions are expected to be quiet for the second and third days (5-6 June). III. Event Probabilities 04 Jun-06 Jun Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
