3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 784 km/s at 10/2120Z. Total IMF reached 20 nT at 11/0310Z. The maximum southward component of Bz reached -2 nT at 10/2214Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 382 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (12 Oct, 14 Oct) and unsettled to minor storm levels on day two (13 Oct). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (12 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: 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 likely to be moderate with a slight chance for an X-class flare on days one and two (12 Oct, 13 Oct) and expected to be low with a chance for M-class flares on day three (14 Oct).
