3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 310 km/s at 03/0648Z. Total IMF reached 9 nT at 03/0805Z. The maximum southward component of Bz reached -7 nT at 03/0709Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 810 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on day one (04 Oct) and quiet to active levels on days two and three (05 Oct, 06 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: 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 expected to be very low with a chance for a C-class flares on days one, two, and three (04 Oct, 05 Oct, 06 Oct).
