COMMENT: MUFs were near predicted to moderately depressed across 
the Australian region during the UT day 26 February. There were 
also isolated cases of Sporadic E blanketing over Australian 
ionosonde sites. For 27 February, MUFs are expected to be moderately 
depressed to near monthly predicted levels due to continued expected 
slight rise in geomagnetic activity and low EUV levels. MUFs 
in the Australian region are expected to return to more normal 
levels on 28 February and 01 March.
