3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 434 km/s at 27/2114Z. Total IMF reached 7 nT at 28/2057Z. The maximum southward component of Bz reached -7 nT at 28/2057Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1596 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (29 Mar), quiet to minor storm levels on day two (30 Mar) and quiet to active levels on day three (31 Mar).
Solar Activity	Analysis of Solar Active Regions and Activity from 27/2100Z to 28/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 8 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 (29 Mar, 30 Mar, 31 Mar).
