3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 712 km/s at 15/1917Z. Total IMF reached 16 nT at 15/1556Z. The maximum southward component of Bz reached -13 nT at 15/1647Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 340 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on days one and two (16 May, 17 May) and quiet to unsettled levels on day three (18 May).
Solar Activity	Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been at 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 May, 17 May, 18 May).
