:Product: 1022RSGA.txt :Issued: 2014 Oct 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 295 Issued at 2200Z on 22 Oct 2014 IA. Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a X1 event observed at 22/1428Z from Region 2192 (S12E06). There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be high on days one, two, and three (23 Oct, 24 Oct, 25 Oct). IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 607 km/s at 21/2101Z. Total IMF reached 5 nT at 22/1510Z. The maximum southward component of Bz reached -4 nT at 22/0454Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 11815 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (23 Oct), unsettled to active levels on day two (24 Oct) and quiet to unsettled levels on day three (25 Oct). Protons have a chance of crossing threshold on days one through three (23-25 Oct). III. Event probabilities 23 Oct-25 Oct Class M 95/95/95 Class X 55/55/55 Proton 35/40/45 PCAF green IV.
