COMMENT: Variable depressions / enhancements observed equatorial/N 
Aus regions. HF fadeout observed most Aus stations following 
an X-class solar flare peaking at 0409UT. Periods of disturbance 
possible days two to three mainly S Aus / Antarctic regions due 
to anticipated elevated geomagnetic activity.
