On 21st March 2010, It emerged from the clouds a blazing light, hovering above a busy street before zipping off silently into the sunset. Just what propelled the strange flying disc across Sydney's skyline may never be known.

This close encounter was over in seconds, but it was enough to convince mother-of-two Fiona Hartigan that she'd just seen a UFO, and she has the photos to back it up. Ms Hartigan said that she got out of her car to take some photos of the sunset, when the amazing events began.

"As I was about to take a picture this black object appeared and then it started to move," she said."It started off about 800m away but it came closer - to about 400m - and then two other little round things appeared from the bright orange light above."There was no noise, it was calm and peaceful but it was very weird."

Ms Hartigan said the main UFO then shot off above Governor Macquarie Drive at Chipping Norton, with the smaller UFOs zipping away in the opposite direction."I don't know how to explain it - I'm still totally bewildered," she said.

The close encounters came as no surprise to UFO Research NSW spokesman Doug Moffett: "It could be some electrical anomaly that no one has ever seen, it could be an extra-terrestrial craft, it could be something else," he said."There does appear to be a blur around the image, which could just be the way it's shaped, or it could be due to its propulsion system.

According to UFO Research NSW there are between 1000 and 1500 UFO sightings in Australia every year.
