2. FORECAST (23 FEBRUARY - 01 MARCH)
Solar:        Low, chance of moderate levels.

Geomagnetic:  Quiet to unsettled. Recurrence suggests
              chance of active periods 27 Feb.

Frequencies:  Near normal. Slight degradation possible
              27-28 Feb at mid to high latitudes.

PEASE NOTE: 
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
