In the IPS magnetometer data for 14 Feb, a weak (12nT) impulse 
was observed at 0611UT.
Frequencies:  
   Cocos Island Region:
      Mostly near predicted monthly values.
   Niue Island Region:
      Near predicted monthly values.
   Northern Australian Region:
      Near predicted monthly values.

2. FORECAST (15 FEBRUARY - 21 FEBRUARY)
Solar: 
Low

Geomagnetic:  
Quiet to Unsettled conditions.

Frequencies:  
MUFs near predicted monthly values is suggested by low number of solar active
regions 
from 27 day solar rotation recurrence.
