:Product: 1029RSGA.txt :Issued: 2014 Oct 29 2245 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 302 Issued at 2200Z on 29 Oct 2014 IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 29/1433Z from Region 2192 (S12W84). There are currently 6 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a chance for X-class flares on day one (30 Oct) and likely to be low with a chance for M-class flares and a slight chance for an X-class flare on day two (31 Oct) and likely to be low with a slight chance for an M-class flare on day three (01 Nov). IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: 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 454 km/s at 28/2128Z. Total IMF reached 6 nT at 28/2143Z. The maximum southward component of Bz reached -5 nT at 28/2349Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1466 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (30 Oct) and quiet to unsettled levels on days two and three (31 Oct, 01 Nov). Protons greater than 10 Mev have a chance of crossing threshold on day one (30 Oct) and have a slight chance of crossing threshold on day two (31 Oct). III.
