regions were mainly near monthly predicted levels on UT day 18 
October. Both the Niue Island region and the Northern Australian 
region experienced Minor MUF depressions during the local day. 
Some sporadic E was observed. The three day outlook (UT days 
19-21 October) is for MUFs to be at near monthly predicted levels, 
with the possibility of periods with Minor depressions.
