COMMENT: IPS HF Communications Warning 23 was issued on 14 July
and is current for 15-17 Jul. MUF depressions of up to 20% have
been seen across much of the Australian region over the last
24 hours. These conditions are due to low levels of ionising
solar flux. IPS HF Warning 15/23 has been issued and is current
for the next 2 days.
