3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 715 km/s at 07/2012Z. Total IMF reached 15 nT at 07/0438Z. The maximum southward component of Bz reached -11 nT at 07/1657Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 564 pfu at 07/1820Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on days one and two (08 Nov, 09 Nov) and quiet to active levels on day three (10 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (08 Nov, 09 Nov, 10 Nov).
Solar ActivityAnalysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 6 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, two, and three (08 Nov, 09 Nov, 10 Nov).
