2. FORECAST (13 FEBRUARY - 19 FEBRUARY)
Solar: 
Solar flare activity is expected to be at the R0 level this week,
with a chance of R1. 

Geomagnetic:  
G0 geomagnetic conditions are expected over 13-15 Feb, with a chance of
G1 on 15-Feb, increasing to G0-G1 conditions over 16-19 Feb due to
coronal hole high speed wind stream effects from a narrow equatorial
coronal hole. 

Frequencies:  
MUFs in the Australian region are expected to be generally near predicted
monthly values, though mild depressions are possible over 16-19 Feb,
particularly
in southern Australian regions, due to mild geomagnetic activity.
