COMMENT: Overall HF conditions were near normal, however in the 
antarctic region there were isolated periods were no foF2 layer 
was detected via the ionosondes and in the equatorial region 
there was a mild depression during the local day. Also noted 
at equatorial and northern Australian regions were isolated cases 
of sporadic E. Over the next several days expect the HF conditions 
to be near normal with isolated cases of sporadic E at equatorial 
and northern Australian regions. Spread F noted on the Hobart 
ionograms.
