3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 603 km/s at 21/1727Z. Total IMF reached 9 nT at 20/2154Z. The maximum southward component of Bz reached -7 nT at 21/0003Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4986 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (22 Apr, 23 Apr, 24 Apr).
Solar Activity	Analysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 4 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (22 Apr, 23 Apr, 24 Apr).
