g'day,

Got a question about an object we've noticed in the sky over Perth. It's been there every day for the past 2-3 weeks between 23:00 and at least 23:45 (haven't looked any later than that). We haven't got any fancy equipment beyond a small pair of binoculars, so the best I can give you is that it's in the sky to the west of Wanneroo and has flashing green and red lights.

At first we thought it may be a plane, but it seemed far too high, and certainly higher than what the planes usually fly at. It occurred to us that it may be star, but it had the flashing lights. The next thought was a satellite, but I reasoned there was no point for a satellite to waste power on flashing lights given the lack of human traffic. I try and keep up on science news and 've not heard of any shuttles going up, so it can't be that.

It's become quite an interesting little mystery here, any ideas you could provide would be much appreciated.
