17 Jan   -30    Normal-fair      Depressed 15 to 30%/near predicted 
                                 monthly values

                                 monthly values   

COMMENT: On UT day 16 January, there were minor to moderate MUF 
depressions across the Niue Island and Australian regions as 
compared to the monthly predicted levels, with some severe MUF 
depressions during the local night in the Northern Australian 
region. In the Antarctic regions, MUFs were near predicted monthly 
values. Sporadic E layers were observed across the Australian 
region and in Antarctica. Similar levels of ionospheric support 
are expected for the next 3 days with MUFs either near predicted 
monthly values or mildly to moderately depressed due to continued 
low levels of ionising radiation from the Sun.
