:Product: 0701RSGA.txt :Issued: 2013 Jul 01 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 182 Issued at 2200Z on 01 Jul 2013 IA. Analysis of Solar Active Regions and Activity from 30/2100Z to 01/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 01/1516Z from Region 1785 (S09E76). There are currently 7 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (02 Jul, 03 Jul, 04 Jul). IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: 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 610 km/s at 01/0338Z. Total IMF reached 5 nT at 30/2106Z. The maximum southward component of Bz reached -4 nT at 30/2342Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5846 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (02 Jul, 03 Jul) and quiet to unsettled levels on day three (04 Jul). III.
