Iridium Flare

Iridium Flare

Iridium communication satellites can reflect sunlight from their antennas directly back to earth, resulting in a bright flash lasting a few seconds. The flares can be so bright that they sometimes damage sensitive astronomical equipment, but they are an impressive sight! Since most iridium satellites are controlled, you can predict when and where the flares appear. An Iridium flare looks like a star that moves slowly and quickly brightens, then slowly fades away.
