COMMENT: Mildly disturbed conditions this week due
to elevated solar wind speeds from solar coronal hole.

 
2. FORECAST (06 FEBRUARY - 12 FEBRUARY)
Solar: Low to Moderate. A solar region (number 551) in the south-east 
       quadrant of solar disk is showing growth, and may begin to produce
       solar flares if it continues to develop. A previously 
       active solar region (number 540) is due back to the solar
       disk around 08 Feb. Activity may increase after this date.

Geomagnetic:  Active periods possible 06 Feb, then mostly quiet 
       to unsettled. A weak recurrent pattern suggests that
       active periods are also possible around 12 Feb.

Frequencies:  depressed 15% briefly after local dawn on 06-Feb, 
       then mostlly near predicted monthly values.

PLEASE 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.
