2 star like things travelling in a curve shape from west to north east, at equal speed, without blinking in the night for 2-3 minutes.i was on my roof around a year back having a walk after dinner with my parents and brother and sister like we usually do. I was looking up when i noticed 2 star like bright dots as if they are moving stars. they were moving in a slow speed like an aeroplane looks like from below flying at 30000 feet. They were moving in a curved shape from west to north east. i had a small telescope on the roof. i tried to find them through it but could only catch a glimpse which looked like a star seen through a telescope. they moved slowly at constant speed , equal distance between them and vanished towards the horizon in 2-3 minutes. They did not like aeroplanes, shooting stars or satellites which we usually see on the roof. they were blinking and did not do anything else and just vanised. We all saw it. though we do not believe in UFO's but it was something like we never saw before. i still have a picture of it in my eyes.
