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 742 km/s at 03/2132Z. Total IMF reached 6 nT at 03/2107Z. The maximum southward component of Bz reached -4 nT at 03/2257Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 3 pfu at 03/2145Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2418 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (05 Apr) and quiet to unsettled levels on days two and three (06 Apr, 07 Apr). Protons have a slight chance of crossing threshold on days one, two, and three (05 Apr, 06 Apr, 07 Apr).
Solar ActivityAnalysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity has been at high 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 moderate with a slight chance for an X-class flare on days one, two, and three (05 Apr, 06 Apr, 07 Apr).
