Report of Solar Geophysical Activity (RSGA)Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 164 Issued at 2200Z on 13 Jun 2013 IA. Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: 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 likely to be low with a slight chance for an M-class flare on days one, two, and three (14 Jun, 15 Jun, 16 Jun). IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: 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 439 km/s at 13/0331Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 786 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (14 Jun, 15 Jun, 16 Jun). III.
