Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (04 Jan, 05 Jan, 06 Jan). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 344 km/s at 02/2155Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 660 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and three (04 Jan, 06 Jan) and unsettled to minor storm levels on day two (05 Jan). III.
