I was at my terrace and sitting idle around 12:o1am in night. I was gazing at sky and I saw it.I knew about the UFO's and its sightings so I analysed that it was an UFO.Object was circular in shape ,there were lights on its sides and it was moving exactly at straight path in a slow motion.I was glad as well as frightened to see it.And I didn't sleep that night.It was moving in slow motion and then it suddenly blew with a high speed.
