COMMENT: On UT day 14 January, there were mild to moderate MUF 
depressions across the Australian region as compared to the monthly 
predicted levels, with some severe MUF depressions during the 
local night in the Northern Australian region. Notable Sporadic 
E layers observed at low to mid latitude stations. 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.
