Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity was at very low levels. The visible solar disk remained spotless. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain at quiet levels throughout the forecast period (23 - 25 January). III.
