3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 505 km/s at 11/2100Z. Total IMF reached 14 nT at 11/2053Z. The maximum southward component of Bz reached -12 nT at 11/2037Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 585 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (12 Jun), unsettled to major storm levels on day two (13 Jun) and unsettled to minor storm levels on day three (14 Jun).
Solar ActivityAnalysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at low 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 (12 Jun, 13 Jun, 14 Jun).
