COMMENT: Maximum usable frequencies (MUFs) on UT day 13-Oct were 
mostly above predicted monthly values by 15-50% enhanced. MUFs 
are expected to be near predicted monthly values to 30% enhanced 
over 14-16 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. Spread F was observed 
during local night hours at Hobart.
