:Product: 0802RSGA.txt :Issued: 2014 Aug 02 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 214 Issued at 2200Z on 02 Aug 2014 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C2 event observed at 02/1328Z from Region 2132 (S19E32). There are currently 10 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (03 Aug, 04 Aug, 05 Aug). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: 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 510 km/s at 02/1332Z. Total IMF reached 9 nT at 01/2112Z. The maximum southward component of Bz reached -8 nT at 02/1353Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (03 Aug) and quiet to unsettled levels on days two and three (04 Aug, 05 Aug). Protons greater than 10 Mev have a slight chance of crossing threshold on day three (05 Aug). III. Event probabilities 03 Aug-05 Aug Class M 55/55/55 Class X 20/20/20 Proton 05/05/10 PCAF green IV.
