:Product: 0724RSGA.txt :Issued: 2016 Jul 24 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 206 Issued at 2200Z on 24 Jul 2016 IA. Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M2 event observed at 24/0620Z from Region 2567 (N05W92). There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on day one (25 Jul) and expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on day two (26 Jul) and expected to be very low with a slight chance for a C-class flare on day three (27 Jul). IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 473 km/s at 24/1453Z. Total IMF reached 13 nT at 24/1512Z. The maximum southward component of Bz reached -11 nT at 24/2006Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 210 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one, two, and three (25 Jul, 26 Jul, 27 Jul). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (25 Jul). III. Event probabilities 25 Jul-27 Jul Class M 40/10/01 Class X 10/01/01 Proton 10/01/01 PCAF green IV.
