:Product: 0310RSGA.txt :Issued: 2014 Mar 10 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 Solar Geophysical Activity Report and Forecast SDF Number 69 Issued at 2200Z on 10 Mar 2014 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was an M1 event observed at 10/1528Z from Region 2002 (S19E37). There are currently 6 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (11 Mar, 12 Mar, 13 Mar). IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 350 km/s at 10/1330Z. Total IMF reached 6 nT at 10/0956Z. The maximum southward component of Bz reached -4 nT at 10/0911Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 103 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (11 Mar) and quiet levels on days two and three (12 Mar, 13 Mar). III.
