:Product: 0814RSGA.txt :Issued: 2014 Aug 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 226 Issued at 2200Z on 14 Aug 2014 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 7 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 flare on days one, two, and three (15 Aug, 16 Aug, 17 Aug). IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: 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 418 km/s at 13/2149Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 201 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (15 Aug, 16 Aug) and quiet levels on day three (17 Aug). III.
