Strange symmetrical disk shaped lightsI was travelling in a train from Ludhiana to Delhi. I was sitting near the window and staring at the lights outside. It was a bit cloudy. I was amazed to see light yellow light in the clouds. When i looked down i saw some lights far off from the train. Lights were glowing as though they were on the outer side of a disk. First i thought it must be a cricket stadium or some flyover but when i observed the lights for over half an hour i was shocked as those lights didn't change their position as my train was moving at a speed of over 60Kms per hour. I continued to stare at the lights till 1:00 for over 50 minutes when they were obstructed by the city buildings. There was no flash coming from them . they were dim just like stars and their position was stationary relative to my train (just like stars) which made me believe that its something not on the ground but in the sky. There were 2 symmetrical patterns of lights as though there are 2 disks . It might have been a spy plane or something but in that case , it should have changed its position when my train stopped at a station for over 10 minutes . But this didn't happen. When my train started again, the lights were still at the same position.
