Clouds aren't the only reason why we don't see a lot of stars in Rochester. Light pollution makes it tough to see the stars under the best conditions. If you're wondering about the darkness of the night sky where you live, you might be interested in joining the Globe at Night project. Starting tomorrow night, observers around the world will follow the instructions at that site and report their observations. Since it is March in Rochester, the amazingly accurate Clear Sky Clock will help you decide whether you'll see stars or clouds.
