Was looking out window at early hours when i seen somthing what looked like a usual star slightly brighter but practically the same as most but this was already moving high up there i've seen things like this that can be accounted for as natural phenomenons, but this one stopped in its path for a few seconds doubled back in a almost straight path stood still then made a curved kind of path as it done this stood still aggain then it kind of glowed a little brighter and done somthing what reminded me of a loop the loop manoeuvre but maybe a half circle but midway during the half loop glowed most intense,it then returned to its usual brightness casually drifted a short distances in the sky then stopped abruptly and blended so well i lost it with the stars.
