    Kevin,
    
    I last saw 02-009B/27387 in 5 different passes from May 4th through
    June 22nd, 2002 and its apparent magnitude ranged from [approximately]
    3.1 to 5.0, corresponding to quicksat intrinsic magnitudes of 3.3 +/- 0.6
    (or [Matson's] Skymap standard magnitudes of 4.6 +/- 0.5.
    
    As to 02-009A/27386, in four passes from April through August 2002, it
    was a little brighter, its quicksat intrinsic magnitude being 2.7 +/- 0.8
    (and Skymap standard magnitude 4.0 +/- 0.9).
    
    In my light-polluted environment, I need binoculars to reliably see
    an object much fainter than about third magnitude, so neither object
    was ever really easy for me to see naked eye.
    
    When I have a chance, I'll try to see these objects and see if, as you
    observed, the rocket has significantly dimmed.
    
    Clear and dark skies!
