3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 585 km/s at 09/2047 UTC. Total IMF reached 12 nT at 09/1516 UTC. The maximum southward component of Bz reached -10 nT at 09/1027 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 766 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to active levels on day one (10 Jul), quiet to active levels on day two (11 Jul) and quiet levels on day three (12 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity has been at moderate 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 (10 Jul, 11 Jul, 12 Jul).
