3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field has been at NA levels for the past 24 hours. Solar wind speed reached a peak of 369 km/s at 20/2356 UTC. Total IMF reached 4 nT at 21/1857 UTC. The maximum southward component of Bz reached -3 nT at 21/2118 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 585 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (22 Sep), quiet to active levels on day two (23 Sep) and quiet to minor storm levels on day three (24 Sep).
Solar ActivityAnalysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: 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 (22 Sep, 23 Sep, 24 Sep).
