COMMENT: Variable enhancements / depressions observed Equatorial/N 
Aus regions. Shortwave fadeout observed briefly E Aus and for 
1 hour W Aus following M-class solar flare 0350UT. Weak ionosphere 
Antarctic region with increased absorption local day. Expect 
continuing moderate geomagnetic disturbances day one. Little 
ionospheric support expected Antarctic region days one and two. 
Disturbances possibly extending at times to S Aus region. Variable 
conditions likely Equatorial / N Aus regions. Expect further 
geomagnetic disturbance affecting S Aus/NZ/Antarctic regions 
days two and three
