3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 542 km/s at 11/1806 UTC. Total IMF reached 8 nT at 11/1742 UTC. The maximum southward component of Bz reached -4 nT at 11/1857 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4619 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (12 Jul), quiet to unsettled levels on day two (13 Jul) and quiet levels on day three (14 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 4 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 and two (12 Jul, 13 Jul) and likely to be low with a slight chance for an M-class flare on day three (14 Jul).
