Have you ever watched the International Space Station move overhead? If it flies over about an hour after sunset, you can see the brightly lit ISS move quickly across the sky (assuming not too many clouds, of course). I watched it fly over my head tonight! It was moving fast, crossed the entire sky in about three minutes. NASA has a web site which will send you messages when it is going to pass over your area. You can learn more and sign up for notifications for your location at https://spotthestation.nasa.gov/. Happy hunting!
