COMMENT: Generally expect frequencies to be returning to monthly 
averages today as solar coronal hole effects decline. Next recurrent 
hole expected to take effect on 6th Aug UT. Strong spread F observed 
last night at southern latitudes (esp Hobart and some at Christchurch) 
and may degrade communications with multipath fading if it re-occurs. 
Extensive sporadic E also observed at night at southern latitudes. 
PNG showed a strong nighttime reduction in foF2 which may re-occur 
in the declining phase of the current coronal hole induced geomagnetic 
activity.
