    A brilliant pass in more ways than one.
    
    Maximum magnitude was definitely much more than those predicted by Heavens 
    Above or Calsky.    It was as good as some Iridium flares and may have been 
    as much as -2 or -3.  in a clear sky, one of the few we have had for some 
    time at suitable times for observation.
    
    Through 7 x 50 binoculars I was able to see the shape of the complex.   It 
    faded much more slowly than had been indicated and was visible 1x for most 
    of the pass after shadow exit until it was lost behind the hills which block 
    visibility around 10  degrees elevation here.  As a bonus the complex passed 
    very close to Canopus which was predicted at 0.6 m , the ISS/STS combo was 
    definitely much brighter.
    
    So it does appear that the predictions from the sites may be based on the 
    normal ISS configuration without the shuttle attached.
