    I am not certain this is what you are looking for as it is not called "time
    diagram", but the attached does make LHA a bit more digestible for me. It is
    from Susan P. Howell's book "Practical Celestial Navigation" which I
    purchased from Celestair.  Other texts I own (but are sadly in storage far
    away) may use the same diagram but in the opposite rotation.  The end result
    is the same.
    A question for the list.  When teaching at Purdue I recall copies from a
    book could me made for educational purposes, and "deju duh" (the Indiana
    version of "deju du) causes me to think there was a limit on the number of
    copies.  Am I skirting violation of copyright law by postings excerpts? If
    so, would it be legal to send just one copy off list?
