2. FORECAST (24 MARCH - 30 MARCH)
Solar: Low, no significant active regions currently on disk 
or expected to rotate onto the disk in the coming week.

Geomagnetic:  
Quiet to Unsettled conditions. Possible isolated Active periods 
for Days 1,2 and 3 of this forecast due to a thin coronal hole.

Frequencies:  
MUFs mostly near predicted monthly values, with possible 
depressions of 10%. No SWF expected.
