3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 442 km/s at 12/2218Z. Total IMF reached 6 nT at 13/1427Z. The maximum southward component of Bz reached -3 nT at 13/0512Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5223 pfu at 13/1700Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (14 Nov, 15 Nov) and quiet to unsettled levels on day three (16 Nov).
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 9 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (14 Nov, 15 Nov, 16 Nov).
