3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 707 km/s at 29/2212Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 9213 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (31 Jan, 01 Feb, 02 Feb).
Solar Activity	Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity has been at low 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 slight chance for an M-class flare on days one, two, and three (31 Jan, 01 Feb, 02 Feb).
