2. FORECAST (06 FEBRUARY - 12 FEBRUARY)
Solar: 
R2-R3 level solar activity is expected over 06-09 Feb to to
AR4366. After this region leaves the solar disk R0-R1 level
solar activity is expected over 10-12 Feb.

Geomagnetic:  
G0 conditions are expected for most of the week, with a chance
of G1 on 07-Feb due to a combination of coronal hole high 
speed wind stream effects and a possible glancing CME impact.

Frequencies:  
MUFs are expected to be near predicted monthly values to 
enhanced by 15-30% throughout the week. Shortwave fadeouts
are probable.
