3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 466 km/s at 31/1414 UTC. Total IMF reached 5 nT at 31/1642 UTC. The maximum southward component of Bz reached -5 nT at 31/0020 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2007 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (01 Sep) and quiet levels on days two and three (02 Sep, 03 Sep).
Solar Activity	Analysis of Solar Active Regions and Activity from 30/2100Z to 31/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 6 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 (01 Sep, 02 Sep, 03 Sep).
