    FWIW, while getting ready for work yesterday, I realized 
    that I had not included the time with the position of the 
    Progress!  (This is one of those "still up at 4:00 a.m. 
    local time" errors I tend to commit.)  The rough position 
    I got for the Progress was:
    
    > RA 8:37:59, Dec +64.8 (2000).  
    
    The time was about 3:28:27.8 June 9 UTC.  Quicksat gives
    me these predictions using the same elements:
    
    3:38:27 RA 8:38, Dec +65.0
    3:38:28 RA 8:41, Dec +65.3
    
    So it seems the prediction I had was reasonably close, 
    though it went into the Earth's shadow a little later 
    than I thought:
    
    3:28:35 shadow hgt 1 mile RA 9:12, Dec 67.0
    3:28:36 shadow hgt 0 mile RA 9:16, Dec 67.2
