                                 to 15% enhanced   

COMMENT: Maximum usable frequencies (MUFs) in the Australian 
region were near predicted values to 35% enhanced on UT day 13-Nov. 
Regional MUFs were enhanced after local dawn this morning. MUFs 
are generally expected to be near predicted values to 15% enhanced 
over 14-16 Nov, with mildly degraded conditions possible during 
local night hours for the southern Australian region and possible 
post dawn depressions of 15% on 15-Nov if an anticipated mild 
increase in geomagnetic activity from a coronal hole wind stream 
eventuates on 14-Nov. Isolated minor fadeouts possible.
