COMMENT: Enhanced MUFs observed for Australasian region over
the last 24 hours. Sporadic E-layers at several locations, particularly
partially blanketing the F-layer in the south-west at night.
Normal to enhanced ionospheric support expected to continue for
the Australasian region for the next 3 days with enhanced MUF's
of approx 15%. Geomagnetic activity will gradually increase to
Active levels over 23-25 Dec due to a high-speed solar-wind stream
and this will probably cause more variability in MUFs.
