Three large orange lights, one after another and moving in an arc, seen at night in Western Australia.UFO SIGHTING IN WESTERN AUSTRALIA - May 2016 On Saturday night, 28 May, 2016, between approximately 10.00 - 10.30pm, I witnessed several objects in the night sky that I, and my three travelling companions, believed could be UFOs.All agreed they were not at all similar to a plane, helicopter, flare signal or pyrotechnical display, either in appearance or in the way they traversed the sky.We were driving south, in the Great Southern region of WA, between Narrikup (a small rural settlement) and the city of Albany.The form was a large, bright light in an apricot to mango shade of orange.In size, they were around half way between a star and a full Moon (when the latter is fully risen).I recall that there were three of these (definitely at least two), appearing separately, one after the other.Their trajectory was appearing ahead and to our right, originating from below our line of vision, then moved swiftly in a high arc, progressing to our left while lowering, then vanishing to below our line of vision. The rising point appeared to be closer to us than the vanishing point, i.e. the pathway, from our standpoint, was angled.As mentioned above, they appeared one after the other, with only a few seconds between each occurrence. The entire sighting would have been approximately 20 seconds.
