    Jean-Marie Biets is a meteorphotographer who uses an all-sky camera to
    catch bright meteortrails. We live about 50 km apart (30 miles). Since
    a couple of years Jean-Marie sent me some photographs on which trails
    other than from meteors, ISS or Iridiums have been recorded. He then
    requests me to identify which satellite(s) is (are) responsible for the
    trail(s). Until last May I was able to identify all of them. In this
    way I could positively respond on his requests.
    
    At the end of May I reflected on these kind of observations. In fact it
    mostly concern satellites which flare. These observations support the
    purpose of the PNAS-collection. I requested Jean-Marie to send all his
    photographic records of the type I described above and he likes to do so.
    
    Using Guide 8 I was able to identify all satellites by comparing the
    photographed tracks with the simulated tracks as calculated and displayed
    for the specified time and Jean-Marie's location. Here follows the results
    of my identifications as PNAS-records using JMB as observer's ID.
    
    If a magitude is specified it is my (BD's) estimation. This is also true
    for the determination of time and position.
    As usual the time is that of the flare termination and the duration might
    hve been specified. If no duration is available the specified time is that
    in the middle of the flare,
