An Iridium satellite

The Iridium 96 satellite was launched from Vandenburg AFB at 17:43 (UTC) on the 11th of February 2002. The Delta 7920-10C launch vehicle inserted the satellite into a 776 x 779 km, 86.4° orbit.

On Saturday the 14th March 1025 at 20:03 (GMT) I was in my back garden and spotted the satellite orbiting 954 km away from me. Its near polar orbit took it down from the north and and I saw it travelling at 17000 miles an hour as it passed the Plough. At just after 20:04, the sun was reflected directly at me by one of the large communications antennas. The flare from the satellite was by far the brightest thing in the sky (magnitude -8.2) for a few moments.

The excellent website Heavens Above enables one to predict the exact time and position of an iridium flare, from your location. Below is the map provided by Heavens Above for the event -
