Yellowish/blue sphere seen in gurgaon sky, india.It was around 23:15(pm) , when i was just roaming on my roof top.. to see the fireworks.. (on the eve of diwali, festival celebrated in india).. suddenly i saw a fireball like object approaching towards my side. i thought it might be an aircraft or any cracker... but it was just in a continous sluggish motion and when it passed by me overhead.. it was like some bluish light around a yellowish glowing fireball.at that time i was not having a camera or my cell phone with me to take its photograph..Then i just rushed downstairs to call my mom & dad.. to inform them about the whole incident and also took them upstairs with me.. to catch a glimpse of the unidentified object. but it was our bad luck that it was no longer visible and had escaped in the sky.
