I was sitting in a park on a bench and relaxing. The time was 7.15PM (India time). It was dark. I just saw the sky and I noticed a bright object, looking like a star but little brighter than a star, moving in north-east direction. I watched it for 20 to 30 seconds and it vanished after that. It was going in the top speed and at very high altitude. I was staring the object till it was visible and it was circular in shape.
