COMMENT: IPS HF Communications Warning 26 was issued on 3 June 
and is current for 5-6 Jun. Moderate MUF depressions were observed 
for equatorial and northern Australian regions over the last 
24 hours. MUFs were near predicted monthly values to slightly 
depressed for Southern Australia, with disturbed periods in the 
Antarctic. Similar conditions are expected on 5-Jun. MUF depressions 
of 20-40% across Australia are likely 6-7 Jun due to expected 
geomagnetic activity.
