COMMENT: HF conditions were fair to normal during 28 May with 
mildly degraded conditions observed at times at most locations. 
Mildly degraded conditions are expected again at times for the 
next few days. MUFs showed some localised depressions as the 
ionosphere recovers slower than expected from last weeks mild 
activity. The ionosphere is expected to gradually strengthen 
over the next three days, with MUFs mostly near predicted monthly 
values.
