COMMENT: Mild MUF depressions were observed in the north on 19 
Aug. MUFs were near monthly predicted values otherwise. Periods 
of sporadic-E were observed at Cocos Island 20-21 UT. Degradations 
in HF conditions are likely 20-21 due to continued low levels 
of ionising radiation and the anticipated increase in geomagnetic 
activity during this period.
