3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 725 km/s at 01/0313Z. Total IMF reached 9 nT at 31/2151Z. The maximum southward component of Bz reached -7 nT at 31/2304Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5350 pfu at 01/1550Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (02 Nov) and quiet levels on days two and three (03 Nov, 04 Nov).
Solar ActivityAnalysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 2 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 (02 Nov, 03 Nov, 04 Nov).
