3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 334 km/s at 31/1927Z. Total IMF reached 7 nT at 31/1953Z. The maximum southward component of Bz reached -4 nT at 31/0008Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 17 pfu at 30/2120Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 932 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (01 Aug, 03 Aug) and quiet to major storm levels on day two (02 Aug). Protons greater than 10 Mev have a chance of crossing threshold on day one (01 Aug) and have a slight chance of crossing threshold on day two (02 Aug).
Solar ActivityAnalysis of Solar Active Regions and Activity from 30/2100Z to 31/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 8 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, two, and three (01 Aug, 02 Aug, 03 Aug).
