Moved like it curved,had white/blueish lights, whistling.

As I was outside smoking a cigarette, I was speaking to my wife on the phone. And I was looking up to the sky 212 degrees south west when I saw a circular shape moving in a curve angle too fast to have been a plane or a jet or other aircraft. It made a strange whistling sound. And it vanished too fast towards the top of the mountains. It was too close and yet did not make a loud sound just a light whistle. And at first I did not know what to think of but as I gained myself back I was a little spooked.
