COMMENT: MUFs were near monthly predicted values in the mid- 
and low-latitude regions of Australia on UT day 07 December. 
Minor depressions were observed in the high-latitude Australian 
regions. Over the next three days (08-10 December), the high 
latitude depressions are expected to extend into the low latitude 
regions as disturbed geomagnetic conditions persist. HF users 
are advised to use lower than the monthly predicted frequencies.
