COMMENT: Mostly normal HF conditions in the Aus/NZ region over 
the last 24 hours. MUFs were depressed 10 to 20% across the Aus/NZ 
region, particularly during the day. The depressions were due 
to continuing low solar activity. The equatorial regions saw 
some large fluctuations in MUFs over the day with enhancements 
and depressions of up to 35%. Some weak geomagnetic activity 
expected on 27 Feb may provide a short lived boost to MUFs and 
further MUF variability in the equatorial region, however the 
ionosphere is expected to continue to be mildly depressed days 
2 and 3 of the forecast period.
