3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field has been at quiet to major storm levels for the past 24 hours. Solar wind speed reached a peak of 469 km/s at 04/2041Z. Total IMF reached 10 nT at 04/1456Z. The maximum southward component of Bz reached -10 nT at 04/1506Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 723 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (05 May, 07 May) and quiet to unsettled levels on day two (06 May).
Solar ActivityAnalysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity has been at moderate 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 chance for M-class flares on days one, two, and three (05 May, 06 May, 07 May).
