3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 630 km/s at. Total IMF reached 9. The maximum southward component of Bz reached -7 nT at. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 414 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one, two, and three (20 Aug, 21 Aug, 22 Aug).
Solar ActivityAnalysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: 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 expected to be low with a chance for M-class flares on days one, two, and three (20 Aug, 21 Aug, 22 Aug).
