Scientific American says: “It’s great to be camping or at some outdoor event and to suddenly say, ‘Hey, look! See that moving “star”? It's the space station.’ Even better—and a little eerie—is to predict an Iridium flare about 45 seconds in advance.”
Description: ISS Detector alerts you when the International Space Station will be visible in your skies, as sunlight is reflected off the station’s expansive solar arrays. (A similar app called ISS Spotter is available for Apple iOS.) ISS Detector also predicts so-called Iridium flares, when Iridium communications satellites passing overhead glint in reflected sunlight for a few seconds, creating a bright flash that may even be visible during the day.
