3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 405 km/s at 02/1052 UTC. Total IMF reached 6 nT at 02/1839 UTC. The maximum southward component of Bz reached 4 nT at 02/0227 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2,371 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (03 Sep, 04 Sep, 05 Sep).
Solar ActivityAnalysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 6 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 (03 Sep, 04 Sep, 05 Sep).
