help me discover it

I can simply say that my friends and I watched something from out of this world... slowly but directly enter the air space above and to the right of us and deliberatly make course. It appeared from the west, above and slightly to the south of us.  Slowly increased in light and proceeded towards our general direction...(think of a florescent light increasing in legnth ). As it approached, it's tail slowly callapsed... behind itself, but the appearrent object surrounded in light remained.  Then it slowly changed directions 90'north........waiting.... hovering overhead...sillently  the light trail behind it compressed... as it deliberatley  manuevred above and again to the right of us. The light began to make a florescent light shape as it began to expand its energy. Then it shot off.... due north. The light increased to  it's irregular leghnth.... morfered into a ball of light and like a tracer bullet .... dissapeared into ablivian>
