3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 381 km/s at 06/1035Z. Total IMF reached 315 nT at 06/0642UTC. The maximum southward component of IMF reached 6 nT at 06/1738UTC. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 12 pfu at 05/2050Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1324 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (07 Sep), unsettled to minor storm levels on day two (08 Sep) and quiet to unsettled levels on day three (09 Sep). Protons have a slight chance of crossing threshold on days one, two, and three (07 Sep, 08 Sep, 09 Sep).
Solar Activity	Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at 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 (07 Sep, 08 Sep, 09 Sep).
