    Depending on the accuracy of your time and culmination estimate,
    and of elsets, there a few - or many - candidates. Some are:
    21:28:46  68 52   5.5 21574 ERS-1
    21:29:37  87 52   5.3 25344 Iridium 73 ?
    21:29:59  69 59   6.5 26320 99057HD
    
    Very close in culmination is Iridium 73?, not in operational orbit.
    No other Iridium flares are predicted this week around that time
    (some before 21:00 BST but higher in the East), so the attitude
    error must be large. This is THE SAME Iridium from which I saw a
    similarly unexpected flare in the S on Aug.1 - see
