COMMENT: An active geomagnetic field resulted in degraded HF 
conditions over the UT day, particularly in the Antarctic regions 
and S.Aus. MUFs however were mostly near predicted monthly values 
to slightly enhanced, typical of a winter ionospheric response 
to geomagnetic activity. There was some variability in MUFs in 
the equatorial regions. Mild MUF depressions are expected 24-25 
April. Continuing variability in MUFs in the equatorial regions 
is also expected.
