    Lacrosse 5 is still doing its odd rapid "disappearance trick"...
    
    An hour ago, I captured it in the act of doing so with my camera, while it was 
    almost overhead for me. See image here:

    This is a 10.7 second exposure, and movement is upwards. Lyra is well 
    recognizable. Some 6 seconds after the start of the exposure, the sat 
    disappears. The end of the trail at the end of the exposure should be between 13 
    & 16 Lyrae (the two stars "above" the trail): but it disappears much earlier.
    
    Note that it wasn't near shadow entry at all.
    
    The sat was perfectly on-time and on-track by the way (position will follow). At 
    the start of the exposure it was mag +1.5
