COMMENT: MUF depressions of up to 30% have been seen across much 
of the Australasian region over the last 24 hours. These conditions 
are due to low levels of ionising solar flux. Disturbed conditions 
also observed Antarctic region due to elevated geomagnetic activity. 
Expect similar conditions next three days.
