3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 423 km/s at 07/1817Z. Total IMF reached 20 nT at 07/1823Z. The maximum southward component of Bz reached -9 nT at 07/1555Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 780 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (08 May, 09 May) and quiet to unsettled levels on day three (10 May).
Solar ActivityAnalysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 4 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 (08 May, 09 May, 10 May).
