3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 585 km/s at 09/2053Z. Total IMF reached 22 nT at 09/1138Z. The maximum southward component of Bz reached -16 nT at 09/1308Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 336 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on day one (10 Feb), unsettled to active levels on day two (11 Feb) and quiet to active levels on day three (12 Feb). Protons greater than 10 Mev have a slight chance of crossing threshold on days one and two (10 Feb, 11 Feb).
Solar ActivityAnalysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C4 event observed at 09/0101Z from Region 3977 (N18W96). There are currently 11 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 (10 Feb, 11 Feb) and expected to be low with a chance for M-class flares on day three (12 Feb).
