Date T index Conditions MUFs
29 Oct -25 Normal Near predicted monthly values

COMMENT: MUFs over the Australian regions were mainly from near
monthly predicted levels to depressed by around 35% on UT day
28 October. Very low levels of ionisation radiation from the
Sun seems to be the main reason for these MUF depressions. Minor
to moderate MUF depressions in the Aus/NZ regions may be expected
for the next three days (UT days 29 to 31 October).
