COMMENT: Maximum usable frequencies (MUFs) on UT day 14-Oct were 
mostly above predicted monthly values by 15-60% enhanced. MUFs 
are expected to be near predicted monthly values to 15% enhanced 
over 15-17 Oct, with mostly good HF conditions expected. Slight 
degradations of HF conditions may occur on 15-Oct due to the 
expected arrival of a CME first observed on 11-Oct. Isolated 
minor shortwave fadeouts are possible.
