2. FORECAST (02 FEBRUARY - 08 FEBRUARY)
Solar: 
R0-R1 early in week. R1 level events may increase in frequency towards end of
week. 

Geomagnetic:  
G1-G2 geomagnetic conditions possible on 04-Feb due to the combination of a
coronal hole and CME impact. 
Chance G1 on 05-Feb due to ongoing effects. G0 on all other days.

Frequencies:  
Near predicted values to 15% depressed over 04-05 Feb. Maximum usable
frequencies (MUFs) may be
near predicted monthly values for the rest of week, becoming enhanced by the end
of the 
week if no further geomagnetic activity occurs.
