COMMENT: MUFs depressions ranging from 10%-30% were observed 
for Equatorial, Northern AUS and Southern AUS/NZ regions over 
the last 24 hours. MUFs were near predicted monthly values for 
Antarctic regions. Notable Sporadic E layers observed from some 
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 depressed due to continued low levels 
of ionising radiation from the Sun.
