3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 509 km/s at 17/1452Z. Total IMF reached 12 nT at 17/0535Z. The maximum southward component of Bz reached -6 nT at 17/0803Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1012 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (18 Jun) and quiet to active levels on days two and three (19 Jun, 20 Jun).
Solar ActivityAnalysis of Solar Active Regions and Activity from 16/2100Z to 17/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on day one (18 Jun) and expected to be low with a slight chance for an M-class flare on days two and three (19 Jun, 20 Jun).
