COMMENT: Due to low levels of ionising radiation and enhanced 
geomagnetic activity levels, minor to moderate MUF depressions 
and degradations in HF conditions were observed in the Aus/NZ 
regions today (UT day 17 October). Nearly similar HF conditions 
may be expected in this region on 18 October. Improvements to 
mostly normal levels are expected in HF conditions through 19 
and 20 October as the geomagnetic activity is expected to weaken 
during this period.
