The First Iridium Flash I See Tonight

Ever look up to the night sky and see a star that seems to move a little? Or one that dissappears? If it wasn't a meteorite or a comet, it was probably an Iridium Flash (or satellite flare). There are hundreds of active man-made satellites orbiting this rock we call home. And they all have these super shiny parts. So, when they turn to a certain angle they directly reflect the Sun's light back to Earth.
If you want to know when to look up and see one of these flashes, you can check out Heavens Above, a site that provides tracking information for satellites and other heavenly bodies.
