3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 508 km/s at 29/2323Z. Total IMF reached 15 nT at 30/1837Z. The maximum southward component of Bz reached -11 nT at 30/1748Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5687 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (01 Jul), quiet to active levels on day two (02 Jul) and quiet levels on day three (03 Jul). Protons have a slight chance of crossing threshold on days one, two, and three (01 Jul, 02 Jul, 03 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: 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 likely to be moderate with a slight chance for an X-class flare on days one, two, and three (01 Jul, 02 Jul, 03 Jul).
