COMMENT: On UT day 02 March, MUFs were Mildly depressed to near 
monthly predicted levels over most Australian region as a consequence 
of very low levels of ionising radiation from the Sun and increased 
geomagnetic activity. Sporadic E layers were observed over some 
Australian ionosonde 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.
