i was riding in the car with my dad through the city and i was looking up at the night sky. When i noticed a star like object moving across the sky pretty fast, then suddenly it stopped. Then dissapeared. It was moving in a westarly direction not changing course, just smoothly traveling west. Until it stopped then vanished.I thought it could have been a plane but it had no colours comming from it, (just a white star like object) it was very high up so that just made me believe it could have been the International Space Station however i'am doubtful it could just disappear. To be honest i didnt think much of it until i seen it disappear. When it did i felt quite... excited and also curious at what it was.
