3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 339 km/s at 28/2251Z. Total IMF reached 4 nT at 29/1834Z. The maximum southward component of Bz reached -2 nT at 29/1012Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5621 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (30 Sep, 01 Oct) and quiet to minor storm levels on day three (02 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 2 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on days one, two, and three (30 Sep, 01 Oct, 02 Oct).
