3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 572 km/s at 26/2140Z. Total IMF reached 5 nT at 26/2114Z. The maximum southward component of Bz reached -4 nT at 27/1332Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 11786 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (28 Feb) and unsettled to active levels on days two and three (01 Mar, 02 Mar).
Solar Activity	Analysis of Solar Active Regions and Activity from 26/2100Z to 27/2100Z: 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 chance for M-class flares on days one, two, and three (28 Feb, 01 Mar, 02 Mar).
