COMMENT: MUFs were near monthly medians except at polar latitudes 
due to geomangeitc activity from slow CME on 11th Oct finally 
glancing the geomagnetic field. There a possibility of fadeouts for 
the next three days due to expected increase in flare activity 
associated with AR 1112. Otherwise, expect near predicted MUF 
values for the next three days. The M flare on 16th had a an associated coronal 
shock speed measured but as yet no CME reported.
