COMMENT: Generally expect frequencies to be returning to near
monthly averages today as solar coronal hole and merging of solar-geomagnetic
fields effects decline. Next recurrent hole expected to take
effect on 6th Sept now seems unlikely. Very low ionistation from
AR970 may delay ionospheric recovery from last few days depression.
Strong sporadic E was observed at stations across a wide range
of latitudes and longitudes (Darwin, Canberra, Hobart, Nuie),
particularly at night. Spread F was also observed at night across
a range of latitudes to the east (Hobart, Nuie).These have occurred
on several nights this week and may degrade communications if
re-occurring.
