:Product: 0103RSGA.txt :Issued: 2016 Jan 03 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 3 Issued at 2200Z on 03 Jan 2016 IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 3 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 flares on days one, two, and three (04 Jan, 05 Jan, 06 Jan). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: 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 533 km/s at 03/0524Z. Total IMF reached 9 nT at 03/0304Z. The maximum southward component of Bz reached -6 nT at 03/0429Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 02/2105Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 6782 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (04 Jan), quiet to unsettled levels on day two (05 Jan) and quiet to minor storm levels on day three (06 Jan). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (04 Jan). III. Event probabilities 04 Jan-06 Jan Class M 05/05/05 Class X 01/01/01 Proton 15/01/01 PCAF green IV.
