    Method: Canon Digital Ixus 400 + ASTRORECORD astrometric software.
    Camera at manual mode, "10 second" (= 10.7 second) exposure, wide field
    f2.8/7.41 mm.

    One point on 96-072A has been dropped because of noise interference to the trail 
    end, making it suspect.
    
    05-052A points are on a nice mag 0 flare image. 00-047A points are on a nice 
    mag. +0.5 flare predicted by Phil Masding.
    
    I also captured Kosmos 1315r (81-103B) as a stray but the trail ends did not 
    resolve well. As it was flaring I probably only captured the brightest part of 
    the trail.
    
    Flares seen:
    05-042A: to mag 0 at 20:21:25 UTC
    96-072A: to mag -1 at 20:34:30 UTC
    00-047A: to mag. +0.5 at 21:46:17 UTC (predicted by Phil Masding)
    81-103B: to mag +2 at 21:32:30 UTC
    
    Plus two Iridium flares.
