3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 445 km/s at 11/2036Z. Total IMF reached 10.2 nT at 11/1041Z. The maximum southward component of Bz reached -8.4 nT at 11/1358Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 733 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (12 Aug, 13 Aug) and quiet to active levels on day three (14 Aug).
Solar Activity	Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 4 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 days one, two, and three (12 Aug, 13 Aug, 14 Aug).
