similar conditions may be expected during the first half of 30 
September. Minor to significant degradations in HF conditions 
may be expected through the second half of 30 September and on 
01 October due to an expected rise in geomagnetic activity levels 
during this period. HF conditions are expected to return to normal 
levels on 02 October.
