3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 746 km/s at 13/2147Z. Total IMF reached 7 nT at 14/1405Z. The maximum southward component of Bz reached -2 nT at 14/1704Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 16 pfu at 14/0950Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 534 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (15 Nov), quiet to minor storm levels on day two (16 Nov) and unsettled to minor storm levels on day three (17 Nov). Protons have a chance of crossing threshold on day one (15 Nov), have a chance of crossing threshold on day two (16 Nov) and have a slight chance of crossing threshold on day three (17 Nov).
Solar ActivityAnalysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been at high levels for the past 24 hours. There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a chance for X-class flares on days one and two (15 Nov, 16 Nov) and likely to be moderate with a slight chance for an X-class flare on day three (17 Nov).
