    A hazy sky and a moon high in it made for louzy conditions. The images were 
    quite fogged, but the trails of the objects above nevertheless well defined.
    
    96-072A and 09-061B were having a race against each other, moving in parallel, 
    and while observing them I was not sure which of the two objects was the KH.
    
    05-042A initially was very bright short after emerging from eclipse. It was 2.9s 
    late on 2 day old elements.
    
    I was very tired (have been giving two rather intensive classes the past two 
    days) and hence things went wrong: I mis-aimed the camera while trying to 
    hastily get more images on 96-072A and the 2nd object (later identified as 
    09-061B); and lost track of time for a moment while waiting for 05-042A. Luckily 
    it was bright when it appeared from eclipse: I suddenly saw the very bright 
    satellite moving across the sky, woke up from my temporary absence of mind, 
    looked at the clock, realized I was too late with triggering the first image, 
    said a word I will not repeat here and hastily re-aimed the camera and started 
    to make exposures....
