3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 642 km/s at 13/0146Z. Total IMF reached 8 nT at 13/1046Z. The maximum southward component of Bz reached -7 nT at 13/0337Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 3574 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (14 Jan), quiet to unsettled levels on day two (15 Jan) and quiet levels on day three (16 Jan).
Solar ActivityAnalysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 3 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 (14 Jan, 15 Jan, 16 Jan).
