Date:
June 25, 1973
Location: Dundurrabin, Australia
On
about 25 June, members of the Dorrington family observed
a large, disc-shaped UFO for about 15 minutes between
6.30 and 7.00 p.m. The whole of the object was surrounded
by a green glow. There appeared to be a rotating, brilliant
red light around the middle of the object. A V-shaped
green 'solid' beam seemed to oscillate up and down. This
sighting occurred during a flap in the area of two small
timber towns, Tyringham and Dundurrabin.

One
of the more frustrating aspects of researching the UFO
phenomenon is its unpredictability. One of the mainstays
of the scientific method is the repeatable experiment
and observation. In the case of an unpredictable and elusive
phenomenon, this is rather hard to organise. But occasionally,
UFO phenomena do occur in specific localities for an extended
period. These are referred to as localised 'flaps'.
In
the middle of 1973, a remote locality between Armidale
and Grafton, around two small timber towns called Tyringham
and Dundurrabin, provided me with an opportunity for repeatable
observations. It started with locals observing unusual
light phenomena and other strange occurrences. Details
about the situation came to my notice shortly after they
began. I was fortunate that the strange activity persisted
for months and knowledge of it remained largely limited
to locals and researchers like myself.
On
about 25 June, members of the Dorrington family, at Dundurrabin,
observed a large, disc-shaped UFO for about 15 minutes
between 6.30 and 7.00 p.m. It hovered over Boney Mountain.
The whole of the object was surrounded by a green glow.
There appeared to be a rotating, brilliant red light around
the middle of the object. A V-shaped green 'solid'
beam seemed to oscillate up and down, more than a
dozen times, before retracting into the main object. It
disappeared from view, after 15 minutes, by moving straight
down behind the mountain. The size estimates pointed out
to me on site suggested a very large object.
