3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 317 km/s at 23/2041 UTC. Total IMF reached 14 nT at 23/2043 UTC. The maximum southward component of Bz reached -4 nT at 23/2028 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1111 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (24 Sep) and quiet to active levels on days two and three (25 Sep, 26 Sep).
Solar Activity	Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 9 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 (24 Sep, 25 Sep, 26 Sep).
