3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field has been at quiet to major storm levels for the past 24 hours. Solar wind speed reached a peak of 374 km/s at 08/1638Z. Total IMF reached 19 nT at 08/0751Z. The maximum southward component of Bz reached -18 nT at 08/1143Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 472 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (09 Aug, 11 Aug) and quiet to unsettled levels on day two (10 Aug).
Solar ActivityAnalysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 5 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 (09 Aug, 10 Aug, 11 Aug).
