3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 05/2100Z to 06/2100Z: he geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 574 km/s at 05/2329Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 10956 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (07 Oct), quiet levels on day two (08 Oct) and quiet to major storm levels on day three (09 Oct). Protons have a slight chance of crossing threshold on days one, two, and three (07 Oct, 08 Oct, 09 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at moderate 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 (07 Oct, 08 Oct, 09 Oct).
