3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 407 km/s at 13/2223 UTC. Total IMF reached 11 nT at 14/1124 UTC. The maximum southward component of Bz reached -07 nT at 14/1014 UTC. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 5 pfu at 14/1520Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4652 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on days one and two (15 Sep, 16 Sep) and quiet to active levels on day three (17 Sep). Protons have a slight chance of crossing threshold on days one, two, and three (15 Sep, 16 Sep, 17 Sep).
Solar Activity	Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 4 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 (15 Sep, 16 Sep, 17 Sep).
