3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 435 km/s at 04/1321Z. Total IMF reached 8 nT at 04/0625Z. The maximum southward component of Bz reached -8 nT at 04/0424Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2702 pfu at 03/2220Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (05 Nov), quiet to minor storm levels on day two (06 Nov) and unsettled to minor storm levels on day three (07 Nov).
Solar ActivityAnalysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity has been at 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 low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (05 Nov, 06 Nov, 07 Nov).
