3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic field has been at unsettled to major storm levels for the past 24 hours. Solar wind speed reached a peak of 597 km/s at 31/1803Z. Total IMF reached 13 nT at 31/1514Z. The maximum southward component of Bz reached -11 nT at 31/1735Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 562 pfu at 31/1710Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on day one (01 Nov), quiet to unsettled levels on day two (02 Nov) and quiet levels on day three (03 Nov).
Solar ActivityAnalysis of Solar Active Regions and Activity from 30/2100Z to 31/2100Z: Solar activity has been at very 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 (01 Nov, 02 Nov, 03 Nov).
