COMMENT:  Ionospheric conditions returned to normal levels in 
Northern Australian/Pacific regions and to slightly below normal 
levels in other Australasian regions for the UT day. Ionospheric 
support was still weak, however. Strong sporadic E was observed 
in Northern Australian/Pacific regions and weak sporadic E in middle 
and Southern Australian regions especially early in the UT day, 
degrading communications. Expect propagation conditions to continue 
to improve over the next 24 hours.
