Circular,silently moving object, radiating golden yellow light in dark evening sky.My parents on their way to market, around 7.30 pm on their two-wheeler. While crossing the bongaigaon bridge my mother sitting on backside of two-wheeler noticed something very big,circular ball like object, radiating golden yellow lights,very very prominent,moving fast but very noticeable,silently in the sky. She saw it coming from east-side & moving towards the west border side. My father could not see as he was driving the vehicle focussing down the road. But my mother said first time in her life she saw something like this,it was not a fire-work kind,it was much bigger,full of light,silent and moving smoothly like a vehicle in the dark evening sky. Today my mother told this to me,thought of reporting her descriptions here.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
