COMMENT: HF conditions in the equatorial and northern Australian 
region may be slightly depressed over the next several days most 
likely due to low ionization, resulting from very low levels 
of solar activity. Note, isolated cases of sporadic E occurred 
in the equatorial and Antarctic regions and may continue over 
the next several days.
