Australian and Antarctic regions due to geomagnetic activity,
as well as mild depressions in the North Australian and Equitorial
regions due to low ionisation levels in the ionosphere. Noted
a extended duration of sporadic E at Vanimo between 15-20 UT,
as well as isolated cases of sporadic E at other stations in
the Australian regions.
