3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 606 km/s at 08/1133Z. Total IMF reached 19 nT at 08/0146Z. The maximum southward component of Bz reached -12 nT at 08/0749Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 452 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (09 May, 10 May, 11 May).
Solar ActivityAnalysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity has been at 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 low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (09 May, 10 May, 11 May).
