very bright glowing object that disappeared completely after 1 minute approx.As i was having a walk before going to bed on my terrace , I saw a noiseless spherical figure with a very bright glow .First i thought i might be a plane , but every plane blinks a red flashlight after 1-2 seconds during night .But in this case there was no blinking . it was continuous bright light and approximately after 1 minute the object got vanished .The speed of the object was similar to a low speed plane.
