COMMENT: MUFs were mostly near monthly predicted values across
the Aus/NZ regions for 27 Aug. Poor ionospheric support for Antarctic
regions due to elevated geomagnetic activity. Incidents of sporadic-E
were observed across Australia. Mildly depressed MUFs for Southern
AUS/NZ regions and continued periods of disturbed ionospheric
support for Antarctic regions are expected for 28-29 Aug due
to recent geomagnetic activity. MUFs are expected to return to
near predicted monthly values by 30 Aug for all regions.
