3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 412 km/s at 13/0153 UTC. Total IMF reached 7 nT at 13/2059 UTC. The maximum southward component of Bz reached -5 nT at 13/1931 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 397 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to active levels on day one (14 Aug), quiet to active levels on day two (15 Aug) and quiet to unsettled levels on day three (16 Aug).
Solar Activity	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 7 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 Aug, 15 Aug, 16 Aug).
