3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 548 km/s at 01/2119Z. Total IMF reached 6 nT at 02/0826Z. The maximum southward component of Bz reached -4 nT at 02/1646Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4925 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (03 Jul), quiet to active levels on day two (04 Jul) and quiet to unsettled levels on day three (05 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 11 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (03 Jul, 04 Jul, 05 Jul).
