2. FORECAST (22 JANUARY - 28 JANUARY)
Solar: Moderate activity possible early in week due to new
active region 1041, otherwise Low solar activity is 
expected.

Geomagnetic:  Mostly Quiet to Unsettled conditions. No recurrent
coronal hole activity.

Frequencies:  MUFs near predicted monthly values with possible
enhancements due to increased solar x-ray flux levels. Small
chance of SWF.
