3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 430 km/s. Total IMF reached 5 nT. The maximum southward component of Bz reached -4 nT. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 627 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (21 Sep, 22 Sep, 23 Sep).
Solar Activity	Analysis of Solar Active Regions and Activity from 19/2100Z to 20/2100Z: 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 (21 Sep, 22 Sep, 23 Sep).
