While standing outside looking toward north star, i briefly observed what appeared to be a light, similar to a star or planet, moving in an arc-like path from polaris toward the big dipper. it moved so that the arc descended towards earth and rose up. after 3 or four seconds, it faded out, similar to how issobservations do. upon researching iss sighting possibilities for this date and time according to my zip code, the iss was not visible in that part of the sky at that time, approximately 6:30 in the morning (am). i also have never observed a light in the sky move in an arc- like path. previous observations made by me of the iss have always shown relatively straight flight paths. again, path was arc, with low part of arc towards earth, very brief, and did not span much distance. brightness of object relative to north star was three quaters as bright, eventually fading out completely. it probably was a satellite, but arc path was odd for sarellite, tight arc, 160 degrees total arc path, appx. from my left to right.
