3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 474 km/s at 07/0638 UTC. Total IMF reached 08 nT at 07/1746 UTC. The maximum southward component of Bz reached -06 nT at 07/2006 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5246 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (08 Jul), quiet to active levels on day two (09 Jul) and unsettled to active levels on day three (10 Jul).
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 3 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 Jul, 09 Jul, 10 Jul).
