values across the Australian region with some depressions in 
the Southern regions on 19 November. Minor to mild MUF depressions 
may be expected on 20 November, especially in the Southern Aus/NZ 
regions due to an expected continued slight rise in geomagnetic 
activity levels on this day. Conditions are expected to remain 
mostly normal on 21 and 22 November.
