:Product: 0719RSGA.txt :Issued: 2016 Jul 19 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 201 Issued at 2200Z on 19 Jul 2016 IA. Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: 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 19/1153Z from Region 2565 (N06W35). There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be low with a chance for M-class flares on days one, two, and three (20 Jul, 21 Jul, 22 Jul). IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 390 km/s at 19/1642Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 7070 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one, two, and three (20 Jul, 21 Jul, 22 Jul). III.
