Bunch of lights, moving very very fast along the sky, and they appeared very high. There were planes in the sky too, so a good reference point for speed. They were travelling what appeared to be 10x the speed of the planes in the sky. The lights moved in an undulating pattern, much like a flock of birds, but some seemed to be moving independently of this flock like pattern. There were approximately 20-30, shaped in what looked like a pointing V in the direction of travel, but the shape often changed as the lights danced and moved in this formation. The thing that shook me most, was the speed in which they appeared to be travelling.

Too high to notice any detail whatsoever other than a multitude of lights dancing around the sky in the direction they were travelling.

I cant be sure on the duration of the sighting, it was probably much less than 40s, sorry. It appeared to be longer, but considering the speed they were moving, it probably was much less. I am in shock at what I saw, no plane (considering there were 3 to 4 across the sky at the time with clear white and red lights (white flashing) could move in the way these bunch of lights did. I am also amazed, and slightly in awe of the fact I may have witnessed something that I can not literally explain away as something earth made considering the evasive moves they did whilst dancing around one another whilst travelling at such speed. I love it!!
