    Flares:
    05-016A: to -1 at 20:32:42? UTC (time uncertain), after this disappeared
    96-072A: to 0 at 20:33:33 UTC
    
    05-016A "re-appearance": 22:17:10 UTC, bright (mag +0.5), then fading to +2.5.
    
    USA 129 was nice and bright while traversing Uma, flaring 10 seconds after the 
    end of my exposure. It was 1.2 s late.
    
    Lacrosse 5 was only briefly seen, flaring and then gone during the 20:33 pass. 
    During it's second pass at 22:18 it initially was invisible, but suddenly 
    appeared below Umi, bright, and then faded. It was on-time, but 0.13 deg off-track.
