    Lacrosse 5 (05-016A), "disappearance trick" at 19:30:17 UTC.
    
    USA 129 (96-072A): nice slow flare to -1 at 20:01:00 UTC; and short flare to +2 
    at 21:38:40 UTC (second pass). Trail of second pass too faint on image to 
    unambiguously measure. First trail image of first pass very crisp and bright.
