Watching tv when an advertisement came on so grabbed a cigarette and went out on the balcony of my 2nd floor apartment. Looking out over mountains (Lizard Range) i noticed a dull light hovering. First i thought a helicopter but then realised no sound. Took my glasses off, blinked, cleaned glasses on t shirt and looked again and it was still there. After about 20 seconds it rose higher and then shot off west at very high speed till i lost sight of it.At first i thought i was seeing things, then i started to think, no, it was definitely something. After coming inside i started to feel a bit spooked.Jumped on the internet and searched ufo sightings and came across this website.
