isolated periods were no foF2 layer was detected via the ionosondes 
and in the equatorial region there was a mild depression at local 
dawn. 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.
