3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been at unsettled to major storm levels for the past 24 hours. Solar wind speed reached a peak of 566 km/s at 19/0827Z. Total IMF reached 13 nT at 18/2334Z. The maximum southward component of Bz reached -7 nT at 19/0032Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1187 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (20 Apr, 21 Apr) and quiet to unsettled levels on day three (22 Apr).
Solar Activity	Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 2 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (20 Apr, 21 Apr, 22 Apr).
