:Product: 0714RSGA.txt :Issued: 2015 Jul 14 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 195 Issued at 2200Z on 14 Jul 2015 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: 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 14/1210Z. There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one and two (15 Jul, 16 Jul) and expected to be very low with a slight chance for a C-class flare on day three (17 Jul). IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: 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 513 km/s at 14/0020Z. Total IMF reached 10 nT at 14/2045Z. The maximum southward component of Bz reached -4 nT at 14/0052Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1424 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (15 Jul, 16 Jul, 17 Jul). III.
