3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic field has been at unsettled to active levels for the past 24 hours. Solar wind speed reached a peak of 768 km/s at 28/1010Z. Total IMF reached 13 nT at 28/1703Z. The maximum southward component of Bz reached -12 nT at 28/1522Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 10382 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (29 Jan) and quiet to unsettled levels on days two and three (30 Jan, 31 Jan).
Solar Activity	Analysis of Solar Active Regions and Activity from 27/2100Z to 28/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 10 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 day one (29 Jan) and expected to be low with a slight chance for an M-class flare on days two and three (30 Jan, 31 Jan).
