COMMENT: Minor MUF depressions were observed in the Aus/NZ regions 
for the UT day, 24 October. Current depressions are most likely 
associated with low levels of ionising radiation. Minor to Moderate 
MUF depressions are expected for the next three days due to an 
increase in geomagnetic activity and low levels of ionising radiation. 
Note there were isolated periods of sporadic E observed in the 
Australian region mainly in the latter half of the UT day.
