    Re: Interpolation to latitude

    Hi Inuik,
    I think you may be confused as to where LMT is, regarding this type of 
    exercise.  LMT means at the local zone meridian longitude and the DR 
    latitude.  Sometimes a picture helps - see the attached inuik.gif.
    The time suffix "P" refers to the W45d time zone, sometimes written as "P-3" 
    which means "papa zone is minus 3hr from GMT."  Different letters for 
    different time zones; GMT = "Z" and is the zero longitude time zone, 
    pronounced "zulu."  Notice how I did the calculations in the local "P" time 
    zone, then converted to GMT.
    You can start your computation with LOW LAT TIME = 0447 "Z".  Then your LON 
    CORRN would be 3h 21m, since you started the computation in "Z" time (zero 
    Try it both ways, then stick with whatever floats your boat.  You do want to 
    apply the LAT CORRN first.  The method will then be consistent with the moon 
    event computation method, which needs a "change in LMT" calculation as an 
    entering argument for the LON CORRN.
    But first things first.  Be sure you understand the sun event computations before trying the moon events.
