3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 396 km/s at 17/2033Z. Total IMF reached 13 nT at 17/2019Z. The maximum southward component of Bz reached -12 nT at 17/2014Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 451 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (18 Aug, 20 Aug) and quiet to minor storm levels on day two (19 Aug).
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 4 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 (18 Aug, 19 Aug, 20 Aug).
