3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 519 km/s at 07/2118 UTC. Total IMF reached 17 nt at 07/1047 UTC. The maximum southward component of Bz reached 13 nT at 07/1953 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 428 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on days one and two (08 Sep, 09 Sep) and quiet to unsettled levels on day three (10 Sep).
Solar ActivityAnalysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 7 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 (08 Sep, 09 Sep, 10 Sep).
