3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 578 km/s. Total IMF reached 15 nT. The maximum southward component of Bz reached -11 nT. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 349 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (19 Aug) and quiet to active levels on days two and three (20 Aug, 21 Aug).
Solar Activity	Analysis of Solar Active Regions and Activity from 17/2100Z to 18/2100Z: 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 low with a chance for M-class flares on days one, two, and three (19 Aug, 20 Aug, 21 Aug).
