3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 540 km/s at 06/1800 UTC. Total IMF reached 08 nT at 06/1908 UTC. The maximum southward component of Bz reached -04 nT at 06/1708 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1935 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (07 Jul, 08 Jul) and quiet to active levels on day three (09 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: 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 likely to be moderate with a slight chance for an X-class flare on day one (07 Jul) and expected to be low with a slight chance for an M-class flare on days two and three (08 Jul, 09 Jul).
