Two Iridium Flares

Uploaded by: Kajzar

Monday July 22, 2013

Ksawerów, Poland

Caption: Two Iridium flares. First one's brightness was -7 magnitude (brighter one) and it showed up at 23:01:15 CEST. Second one was -2 magnitude, time 23:01:37 CEST. Distance between them was only 1 degree! I wanted to capture them in the center of the photo but I was standing close to a steel balustrade and my compass didn't show direction too accurately.

Thank you Heidrun and Bill!

Bill, those flares are produced by the Sun reflected from the antennas of Iridium satellites. Those satellites are used to provide satellite telephone calls. If you'd like to know where exactly those flares will show up, search for them for example on Heavens Above site.

Awesome night shots! I have been tracking the Iridium flares and the ISS passing over for the past few months. I use an Android app called ISS Detector and it shows the time and where to look for several space objects as well as the brightness 10
