Interesting formation over east coast AustraliaI watched a formation of 8 lights move across the sky. They appeared to cover a large distance relatively quickly. As they got closer the lights pulsed slightly, changing from orange, to red, to white. The formation alternated, meanwhile, between a zig-zag and straight line.The objects were the size of bright stars, and I estimated to be about two miles to the east. It was dark, and the sky was clear albeit for a slight haze.Shortly after changing to white the objects formed two cirles and emitted trails of sparks as they descended out of my field of view, ie., behind buildings as I walked.Despite having lived near airports, both military and commercial, I had never witnessed anything similar.A possible explanation occurred to me a week later, and I made a few email enquiries.This sighting turned out to be a parachute display team, with flares, operating in darkness for the benefit of the attendees at a local agricultural show. It had me foxed.I'm English, and I'm pretty sure that parachutists don't perform at night in the UK, but laws here obviously don't prohibit such activity.I hope this sighting may be of interest as it could perhaps explain a limited number of other sightings around the globe? It seems the objects were closer than I had realised, thus giving a false impression of speed, and the impressive formation was actually fairly standard for a skilled parachute team!
