near predicted monthly values, with northern Australian region 
MUFs 25% depressed during local night hours. Spread F was observed 
at Hobart and Canberra during local night hours. MUFs are expected 
to be near predicted monthly values over 02-04 Jun, with depressions 
of 15% on 04-Jun due to anticipated geomagnetic activity. Shortwave 
fadeouts are probable.
