3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 548 km/s at 25/0629Z. Total IMF reached 5 nT at 25/0626Z. The maximum southward component of Bz reached -4 nT at 25/1532Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1,064 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (26 Jul), unsettled to active levels on day two (27 Jul) and quiet to active levels on day three (28 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: 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 on days one, two, and three (26 Jul, 27 Jul, 28 Jul).
