3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 472 km/s at NA 09/1425 UTC. Total IMF reached 17 nT at 08/2136 UTC. The maximum southward component of Bz reached -13 nT at 08/2204 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 468 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (10 Aug), quiet to active levels on day two (11 Aug) and quiet to minor storm levels on day three (12 Aug).
Solar Activity	Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity has been at 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 day one (10 Aug) and expected to be very low with a slight chance for a C-class flare on days two and three (11 Aug, 12 Aug).
