COMMENT: On UT day 13 March, MUFs in the Australian region were
mostly near mildly depressed levels in response to the disturbed
geomagnetic conditions associated with the coronal hole. Sporadic
E was observed at times at some stations. Mild MUF depressions
might continue on UT day 14 March in response to recent increase
in geomagnetic activity. MUFs in the Australian region are expected
to be mostly near predicted monthly values on UT days 15-16 March.
