Iridium 24 has a bad attitude, ie orientation no longer stable.

So any flare predicted for it, is not to be trusted.

So you would have seen a flash from it, as the angle between you, the sat and sun, allowed for alot of sunlight to be sent your way.


It shows, which iridium sat's have bad attiudes, so one's no loger reliable for flaring. Look for a " - " beside the name.

 Last night I was taking picture of
 Milky Way and saw a short bright flash
 from a satellite in Pegasus. It was very bright (mag -4 or
 brighter) and
 brief (1 second or less). A faint satellite was visible for
 few tens of
 seconds moving South before fading away.
 The flare is well visible on my picture:
 The path matches well with Iridium 24, but there is no
 predicted flare and
 for a typical Iridium flare this was a very short duration.
 Also the flare
 was seen more than one minute before the satellite should
 have been at the
 flare point. The time was checked from a mobile phone with
 very accurate
 time. It was still 20:02 UT well after the flare.
 Flare time: 2015-09-10T20:01 UT
 Observing site: Muurame, Finland (62.1259N, 25.7019E)
 Could Iridium 24 have been more than minute ahead of the
 prediction and why
 flaring unexpectedly?
