Very bright large flying object moving very fast without any jet contrails in a clear skyWe saw a very bright large object flying southwards (south-east) at high speed in clear sky. Interesting part was that the object did not leave any trail like usual jets and seemed to move faster that usual jets.At first we thought it was the space state but it seem much lower in altitude than the space station after checking the NASA website the timings of ISS do not match.The object was glowing strong white in bright sunlight.May be a satellite but would be too close orbit and much larger for a satellite too.
