Date   T index  Conditions       MUFs                              
07 Oct    -5    Normal           Near predicted monthly values

COMMENT: Overall, MUFs over the Australian region were at slightly 
depressed to near monthly predicted levels on UT day 06 October. 
The highest MUF depression of 30% below monthly predicted levels 
occurred over the Northern Australian regions during the local 
day. The outlook for today (UT day 07 Oct) is for the MUFs to 
return to mostly near monthly predicted values. Depressed MUFs 
are expected to begin from UT day 08 Oct, due to the likely disturbed 
geomagnetic conditions associated with the approaching coronal 
hole.
