Flying across the Atlantic the other day, I saw two "flares". So convinced was I that they were Iridiums that I just made a mental note to check which two they were. However, when I came to run the prediction programs, I could not find any candidates to fit the criteria. Could it have been anything else? The details are as follows: Viewing location: 51.50N 42.67W Date: 28 Dec 1997 Time: 0532UTC Altitude: 36,000 ft Elevation: approx 10 Azimuth: approx 060 Both flared to a mag of approx -5 within ten seconds of each other and lasted 8-10 secs.
