3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field has been at active to severe storm levels for the past 24 hours. Solar wind speed reached a peak of 642 km/s at 04/1242Z. Total IMF reached 24 nT at 04/0032Z. The maximum southward component of Bz reached 18 nT at 04/0113Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 319 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (05 Jul), quiet to active levels on day two (06 Jul) and quiet levels on day three (07 Jul). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (05 Jul) and have a slight chance of crossing threshold on day two (06 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity has been at high levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a slight chance for an X-class flare on day one (05 Jul) and likely to be moderate with a slight chance for an X-class flare on day two (06 Jul) and likely to be low with a slight chance for an M-class flare on day three (07 Jul).
