COMMENT: MUFs were depressed throughout the entire Australasian 
region for most of the day, more pronounced at low latitudes. 
This is due to the continued lack of ionising EUV and X-rays 
from the low spot count on the solar disc. This depressed state 
is likely to continue for the next few days, although slightly 
more sunspot activity is now evident and a pickup may be observed 
in 2-3 days.
