COMMENT: On 21 Jan, MUFs were near predicted monthly values over 
the Australian region. The Cocos Island Region experienced minor 
depressions in MUFs during the local night. An increase in solar 
activity is likely to result in MUFs close to monthly predicted 
values for the next 3 days, though mild depressions in some areas 
are still possible.
