3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 383 km/s at 27/2114Z. Total IMF reached 4 nT at 28/0158Z. The maximum southward component of Bz reached -2 nT at 28/0157Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4128 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (29 Sep, 30 Sep, 01 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 27/2100Z to 28/2100Z: Solar activity has been at very 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 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 (29 Sep, 30 Sep, 01 Oct).
