3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 390 km/s at 14/2317Z. Total IMF reached 5 nT at 15/0359Z. The maximum southward component of Bz reached -5 nT at 15/1425Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 3248 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (16 Apr), quiet to major storm levels on day two (17 Apr) and unsettled to major storm levels on day three (18 Apr).
Solar ActivityAnalysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 3 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 (16 Apr, 17 Apr, 18 Apr).
