a fast bright ligh in skyOn 18th of evening I was standing on my roof and saw a huge flash in the middle of sky and suddenly it took of to a very high speed. It was like few seconds I could see that flash going towards north in very high speed. I am quit fond of spotting meteors and other astronomical activities but never saw such bright fast moving light in the sky. This all happened for like 5 sec but I am damn sure it was a UFO.
