COMMENT: Depressed MUFs of 10%-30% observed for the entire 
Australian/NZ region over the last 24 hours. Disturbed conditions
for Antarctic regions and notable sporadic E observed for IPS Cocos
Is. station between 12UT-22UT. Depressed MUFs of 10%-30% are expected
for the next 2 days for the Australian/NZ region with possible
disturbed conditions for Southern AUS/NZ and Antarctic regions due
to the increased geomagnetic activity from the current geoeffective 
coronal hole. Improved ionospheric support expected by 27Oct 
with occasional depressed MUFs of 10%-20% during local day for 
Northern AUS and Southern AUS/NZ regions and during local night 
for Equatorial regions.
