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 445 km/s at 08/0209 UTC. Total IMF reached 10 nT at 08/1537 UTC. The maximum southward component of Bz reached NA nT at -08 nT at 08/1624 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 3215 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (09 Jul, 11 Jul) and unsettled to active levels on day two (10 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: 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 (09 Jul, 10 Jul, 11 Jul).
