    Hey all:
    I think we have hit the nail on the head.  =)  The sky was still very dark 
    but rapidly brightening as the satellite would have been flying down the 
    back side.  I was hoping to catch it on the up-side.  =)
    Anyways -- on to other things.  I've been trying to collect Delta boosters, 
    hence my interest in Mars Odyessy R/B.  I've observed Deep Space 1 R/B and 
    several GPS R/Bs in the last couple of weeks.
    It will be very interesting to see the decay pattern for Mars Odyssey R/B in 
    the next few months.
    Another object I tried this morning with no success was ERS-1 R/B.
    I live 6 miles from AFETR, and I have seen every launch since August 1995.  
    My favorites have to be Titan IVs.   =)
