3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 501 km/s at 23/2001Z. Total IMF reached 10 nT at 23/0950Z. The maximum southward component of Bz reached -7 nT at 23/1647Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 23/0000Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 681 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and three (24 Oct, 26 Oct) and quiet to unsettled levels on day two (25 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (24 Oct, 25 Oct, 26 Oct).
