3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 439 km/s at 20/2048Z. Total IMF reached 11 nT at 20/1438Z. The maximum southward component of Bz reached -10 nT at 20/1438Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 643 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (21 Oct), quiet to active levels on day two (22 Oct) and quiet levels on day three (23 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 19/2100Z to 20/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 3 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 and two (21 Oct, 22 Oct) and likely to be low with a slight chance for an M-class flare on day three (23 Oct).
