IridiumFlares 1.0

Iridium flares are bright flashes of light produced by the reflective antennas of the Iridium communication satellites.

To observe an Iridium flare, locate the predicted viewing time and direction using a satellite tracking website or app, then position yourself in a dark area with a clear view of the sky.

Iridium flares appear bright because the antennas on the satellites have large, reflective surfaces that reflect sunlight directly towards Earth, creating an intense and short-lived burst of light.

Iridium flares typically last only a few seconds, ranging from 5 to 20 seconds.

Yes, Iridium flares are highly predictable. The timing and location of each flare can be accurately calculated based on the orbital parameters of the satellites.

No, Iridium flares are only visible when the observer is in darkness while the satellite is still illuminated by sunlight.

The brightness of an Iridium flare can vary based on factors such as the angle between the satellite, observer, and Sun; the satellite's orientation; and atmospheric conditions.

The original Iridium constellation consisted of 66 satellites, while the upgraded Iridium NEXT system has 75 satellites in orbit.

You can find predictions for upcoming Iridium flares on various satellite-tracking websites and smartphone apps dedicated to satellite observing.

Yes, you can photograph an Iridium flare by setting up your camera on a tripod, using a wide-angle lens, and using a long exposure to capture the trail of light produced by the flare.
