COMMENT: IPS HF Communications Warning 63 was issued on 13 October 
and is current for 13-15 Oct. Minor to moderate MUF depressions 
and degradations in HF conditions were observed in the Aus/NZ 
regions over the last 24 hours. Nearly similar conditions may 
be expected for the next two days (UT days 15 and 16 October) 
due to continued expected rise in geomagnetic activity levels 
during this period and low levels of ionising radiation. Slight 
relative improvements in HF conditions may be possible on 17 
October.
