3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 676 km/s at 13/2049Z. Total IMF reached 16.3 nT at 13/0027Z. The maximum southward component of Bz reached -8.7 nT at 13/1550Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 329 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to active levels on day one (14 Oct), quiet to unsettled levels on day two (15 Oct) and quiet levels on day three (16 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: 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 (14 Oct, 15 Oct, 16 Oct).
