:Product: Report of Solar-Geophysical Activity :Issued: 2010 Jun 11 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 162 Issued at 2200Z on 11 Jun 2010 IA. Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at very low levels for the past 24 hours. Several B-class events were produced by new Region 1081 (N22W43), which was numbered early in the period today and has a beta magnetic classification. IB. Solar Activity Forecast: Solar activity is expected to be at very low levels with a chance for a C-class event for the next three days (12-14 June). IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain at quiet levels for the next three days (12-14 June). III.
