frequencies were around predicted monthly values during local
day for Southern AUS/NZ and Equatorial regions. Notable depressed
MUFs for Northern AUS regions during this time. Occasional disturbed
periods for Antarctic regions over the UT day. Similar conditions
are expected for the next 24-48 hours. Possible MUF depressions
of 20% for Southern AUS/NZ regions and poor ionospheric support
for Antarctic regions on 12Sep due to increased geomagnetic activity.
