COMMENT: IPS HF Communications Warning 32 was issued on 25 June 
and is current for 26-28 Jun. Variable depressions observed in 
the Australian region due to declining EUV levels related to 
a low number of active regions on the Sun. MUFs are expected 
to remain lower than predicted over the next 3 days due to this 
decrease in EUV. Minor disturbances possible Antarctic region 
day two.
