2. FORECAST (03 FEBRUARY - 09 FEBRUARY)
Solar: 
Solar activity is expected to be at the R0 level for the week. There is
a chance of higher level flaring due to potential returning regions AR3184
and AR3186 which both previously produced X-class flares. These regions 
are due to return over 04-05 Feb, however increased activity over the eastern
limb is yet to be observed.

Geomagnetic:  
G0 geomagnetic conditions are expected.

Frequencies:  
MUFs are expected to be near predicted monthly values to 15% enhanced.
