    Hi all,
    
    Just observed a pass of Lacrosse 5 (05-016A) under somewhat chaotic conditions 
    (involving cats and neighbours...), and saw it disappear and then re-appear again.
    
    Initially it was bright, around mag. 0. I was aiming the camera and about to 
    trigger it when in a few seconds time it disappeared.
    
    This was at about 20:19:30 UTC (+/- 5-10 seconds, I do not entirely trust my 
    memory here for reasons stated below).
    
    It re-appeared again at 20:19:50 +/- 5 seconds at magnitude +1 (this time is 
    stuck better in my memory), close to Capella. The re-appearance was rather quick 
    too, took only a few seconds.
    
     From that point on I could follow it, gradually fading to mag. +2, to beyond 
    Ursa Major where I lost it behind the building. I obtained two trail images 
    following the re-appearance.
    
    The observation was a bit chaotic because my neighbour started a chat with me 
    and I was explaining my observations to her when Lacrosse 5 disappeared (hence 
    why the time of that event did not entirely stuck in my memory. I think it was 
    20:19:30, and certainly not more than 10 seconds before and after that).
    
    Meanwhile her black cat was meowing about and hugging my tripod, which I didn't 
    like because of the camera shaking this could induce, so I gently had to get the 
    animal away from the tripod without offending my neighbour by too harsh 
    countermeasures against her beloved pet.... ;-)
    
    Positions will follow later after I have measured the images...
