:Product: 0922RSGA.txt :Issued: 2014 Sep 22 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 265 Issued at 2200Z on 22 Sep 2014 IA. Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 6 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (23 Sep, 24 Sep, 25 Sep). IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: 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 504 km/s at 22/0035Z. Total IMF reached 6 nT at 22/1508Z. The maximum southward component of Bz reached -5 nT at 22/1559Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 22/1300Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 178 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (23 Sep, 24 Sep, 25 Sep). III.
