COMMENT: Enhanced MUFs observed across all Australian and NZ
regions over the last 24 hours with degraded ionospheric support
for Antarctic regions due to increased geomagnetic activity.
Notable sporadic E observed for IPS Hobart station throughout
the UT day. Normal ionospheric support expected for Australian
and NZ regions for the next 24 hours with enhanced MUF's 15%
for Northern AUS/Equatorial regions. Return to enhanced conditions
for entire Australia and NZ regions for 16Dec to 17Dec as geomagnetic
activity subsides and continued strong ionising EUV flux (f10.7cm)
levels.
