3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 457 km/s at 21/1944Z. Total IMF reached 17 nT at 21/1018Z. The maximum southward component of Bz reached -13 nT at 21/1321Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 869 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on day one (22 Jul) and quiet to active levels on days two and three (23 Jul, 24 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 4 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 days one, two, and three (22 Jul, 23 Jul, 24 Jul).
