COMMENT: MUF depressions of up to 40% have been seen across the 
Australasian region over the last 24 hours. These conditions 
are mainly due to low levels of ionising solar flux and minor 
rise in geomagnetic activity levels. Minor to moderate MUF depressions 
and degradations in HF conditions may be expected for the next 
three days (3, 4 and 5 August) with slightly higher possibility 
of degradations and MUF depressions on 3 August due to expected 
mild rise in geomagnetic activity on this day and continued low 
levels of ionising radiation throughout this period.
