spherical light,bigger than aircraft,travelling west to east,it was lower than some aircraft,like a star but realy in air traffic space

it could have been higher in sky than i thought,but that would have made it massive,it moved west to east past me and my wife in 30 seconds,i observed it with night vision,it got to my extreme left,then just went into speed like nothing man-made ,dissapeared into a dot then vanished,i generaly observe satalites,spacestation etc this was the real deal

ive seen things,following satelies etc,then just shoot off i a different direction,ive seen these thing meet up two ,three,fly in tandem,then just fly off in different directions,alternatively,do the opposite,this i saw tonight was a ufo not man-made for definate,not a star, plane ,satalite it was the best ive seen,and the lowest,their getting bolder.
