Alain Figer posted: >I serendipitously recorded a superb flare by Iridium 4 It appears that the last orbital period correction for Iridium 4 was about 80 days ago. Of course that is too long ago. The following predictions are for a rather random lat/long: 24792 Iridium 8 97 20A 7 12 46 alt 53 azi 91 24796 Iridium 4 97 20E 7 20 19 alt 64 azi 92 24968 Iridium 37 97 56D 7 31 4 alt 80 azi 94 This shows an interval of only 7 minutes 33 seconds from Iridium 8 to Iridium 4 and an interval of 10 minutes 45 seconds from Iridium 4 to Iridium 37. The correct interval should be about 9 minutes 10 seconds. This matches the fact that Iridium 4 has gradually fallen into a lower orbit over the last 80 days due to atmospheric drag.
