:Product: 0307RSGA.txt :Issued: 2011 Mar 07 2200 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 066 Issued at 2200Z on 07 Mar 2011 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been high. Regions 1164 (N24W59), 1165 (S20W78), and 1166 (N11E12) produced M-class events during the past 24 hours, all of which contain a Beta-Gamma-Delta magnetic configuration. Region 1166 produced a M1/Sf observed at 07/1430Z with an associated Type II and Type IV radio sweep. Region 1164 produced a M3 at 07/2012Z with an associated Type II radio sweep and a Tenflare that was in progress at this report time. The SOHO/LASCO imagery observed a full halo CME (a further analysis is underway). Images from the C2 first observed the CME at 07/1448Z while the C3 imagery first observed the event at 07/1518Z. The Penticton 10.7 cm flux and the 90 day mean are estimated for today (07 March) due to flare enhanced readings. IB. Solar Activity Forecast: Solar activity is expected to be moderate on day one (08 March) with M-class events expected. Solar activity for days two and three (09-10 March) are expected to be low with a chance for an M-class event as Regions 1165 and 1164 transit around the west limb. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominantly quiet for the next three days (08-10 March). III.
