- CalSky is a satellite prediction site that can tell you when satellites visibly pass over your area. For example. the Iridium constellation of satellites are hexagonal and can reflect sunlight like a spotlight. Follow the previous link to CalSky, then Satellites>Iridium Flares for a prediction of a flare in your area. These events are fleeting, but the satellite can briefly exceed the brightness of Venus. Remember that in the astronomical system of magnitudes, more negative numbers are brighter. The brightest that Venus can appear is about -4.5. Here is a photograph of an Iridium flare over Lexington, and the International Space Station over northern Minnesota.
