3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 457 km/s at 19/2225Z. Total IMF reached 7 nT at 20/1014Z. The maximum southward component of Bz reached -4 nT at 20/0949Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 14494 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (21 Jul, 22 Jul) and unsettled to active levels on day three (23 Jul). Protons have a slight chance of crossing threshold on days one, two, and three (21 Jul, 22 Jul, 23 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 19/2100Z to 20/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 10 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (21 Jul, 22 Jul, 23 Jul).
