:Product: 0702RSGA.txt :Issued: 2013 Jul 02 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 183 Issued at 2200Z on 02 Jul 2013 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C7 event observed at 02/1749Z from Region 1785 (S11E62). 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 and two (03 Jul, 04 Jul) and expected to be very low with a chance for a C-class flares on day three (05 Jul). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 498 km/s at 01/2136Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4429 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (03 Jul), quiet to unsettled levels on day two (04 Jul) and quiet to active levels on day three (05 Jul).
