3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 567 km/s at 17/0231 UTC. Total IMF reached 7 nT at 17/0148 UTC. The maximum southward component of Bz reached -4 nT at 17/0247 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 584 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (18 Sep), quiet to unsettled levels on day two (19 Sep) and quiet levels on day three (20 Sep).
Solar Activity	Analysis of Solar Active Regions and Activity from 16/2100Z to 17/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 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 (18 Sep, 19 Sep, 20 Sep).
