values to 15% enhanced on UT day 08-Feb with some stronger enhancements 
observed in the northern Australian region during local night 
hours. MUFs are expected to be near predicted monthly values 
to 15% enhanced over 08-10 Feb, with a slight chance of depressions 
late on 10-Feb. MUFs are expected to be near predicted monthly 
values on 11-Feb with a chance of mild depressions due to anticipated 
geomagnetic activity. Shortwave fadeouts are probable.
