Over 20 years ago, Iridium launched a constellation of 66 satellites into space, paving the way for the future of satellite communications. From Earth, unexpected reminders of the constellation’s presence appeared – Iridium Flares, a streak of light in the sky caused by sunlight reflecting off the main mission antenna of an Iridium® satellite. These Flares, which can be seen anywhere in the world, have been likened to shooting stars. As we conduct the largest constellation replacement program in history, known as Iridium® NEXT, our original Block 1 satellites are being deorbited and taking their Iridium Flares with them. Click here to read more about #flarewell.

Join us in saying #flarewell to our Block 1 satellites and help us welcome the future of Iridium NEXT!

Our Network is Global – and So Are Our Flare Superfans!

Fans of Iridium Flares are everywhere. Since the launch of Iridium satellites in 1997, people all over the world have been catching Iridium Flares with their families and friends. Below are some of our favorite images from astronomers and photographers around the globe. To see even more shots, visit CatchTheIridium.com, an Iridium Flare fan site dedicated to capturing images of Flares from each of our legacy satellites before they are gone!

How to Catch a Flare

There are many websites and apps available to help you calculate exactly when a Flare will be visible in your area.

  1. Determine your GPS latitude and longitude coordinates.
  2. Use a website or app to input your coordinates to determine the time and location of an Iridium Flare in your area.
  3. Double-check the prediction shortly before observing, as Flare forecasts can change.
  4. Go outside at least a couple of minutes prior to the time listed on the correct date. (Note: If the sky is not clear, you likely won’t be able to see the Flare.)
  5. Look in the direction of the Flare forecast.
  6. Don’t forget to snap a pic for Instagram or Twitter and tag #flarewell!

So how does this one work for you @IridiumBoss @catchtheiridium and y‘all? BTW it’s not just the exposure - SV60 and the flareplane really “met“ at the intersection point! It looked as if there would be an instant #flarewell ✨

Friday night, #Iridium 95.

The reentry of the Iridium-18 satellite from the older @IridiumComm constellation NORAD ID 1997-034D is now set for August 19th at 14:04 UT+/-13 hours: https://t.co/sdCMYOmbVx #flarewell

I like this one: How SV 97 shyly wants to pass through Perseus and those two chaperoning planes try to cut it off 😉🤩 #flarewell @catchtheiridium

Caught the slowly deorbiting SV5 briefly flashing on the left. The rest is when life intervenes with my plans 😂 #flareplane #flarewell 😂 @catchtheiridium

We don’t yet have tipsy #IridiumFlares, do we? I could offer SVs 95 and 31. A whole lotta shakin‘ #flarewell going on 🤩😂 @catchtheiridium @IridiumBoss

Thursday night, #Iridium 58 & 59. Less than 2 minutes apart and I didn't move the camera.

Communities around the world celebrate Iridium Flares

Our Commitment to Space

As a leader in the satellite communications industry and operator of the world’s preeminent Low-Earth Orbit (LEO) satellite constellation, Iridium is committed to both ensuring the sustainability of LEO in the future and serving as the leading example of what it means to be a responsible steward of space.

For these reasons, we are carefully deorbiting our legacy constellation of Block 1 satellites as part of the Iridium NEXT satellite replacement program. When approaching retirement, each Block 1 satellite is put on an ‘end-of-life’ plan that carefully choreographs the time and location of its decommissioning, leading to its eventual disintegration in Earth’s atmosphere. By doing so, we maintain the highest standards of space debris mitigation and help ensure the sustainability of space for the future.
