2. FORECAST (05 APRIL - 11 APRIL)
Solar: 
Solar activity is expected to be at the R0 level over the 
week of 05-11 Apr. With a chance of R1 if more complex
sunspot regions appear on the disk or rotate over the 
eastern limb.

Geomagnetic:  
G0 geomagnetic conditions are expected for the week of
05-11 Apr, with a chance of G1 on 05-Apr due to ongoing
coronal hole high speed wind stream effects. 

Frequencies:  
MUFs are expected to be near predicted monthly values for
the week of 05-11 Apr, with the possibility of mild 
depressions over 05-06 Apr in the southern Australian 
region due to possible geomagnetic activity on 05-Apr.
