Question

How to predict Iridium Flare?

Answer 1

Use a prediction program and input your coordinates to determine the time and location of an Iridium flare in your area.

Find your location using one of the options listed.

After submitting your coordinates, find a section that says, "Iridium Flares". ...

Find an Iridium flare listed (the time listed is 24-hour local time).

Answer 2

When reflective panels on the satellite catch the Sun at just the right angle, you'll see the satellite rapidly brighten and then quickly fade. Taking pictures of Iridium flares is easy. Once you know where to look, mount your camera on a tripod, set the lens aperture to wide open and expose for 15 to 30 seconds.
