COMMENT: Periods of minor to mild MUF depressions were observed 
today, mainly on low and mid latitudes. The reason for these 
depressions is not clear at the time of this report. Mostly normal 
HF conditions may be expected on 16 June with the possibility 
of minor to mild MUF depressions towards the end of this day 
and then also on 17 June due to expected rise in geomagnetic 
activity levels around this period. Mostly normal HF conditions 
may be expected on 18 June.
