    Lewis and Clark lunars: 1803 Almabnac data
    From: George Huxtable
    Date: 2004 Apr 12, 15:27 +0100

    Relevant to those 1803 lunar distances by Lewis and Clark.
    
    I can quite some relevant extracts from the 1803 Nautical Almanac that I
    jotted down at my last library visit-
    
    Astronomical times and dates, of course, starting at noon each day, 12
    hours after the start of the civil day with the same name and date.
    .
    All times Greenwich Apparent time.
    
    Sun
                     RA             Dec        EOT (sub)
    2 Dec noon  16h 30m 54.1s  S21deg 53' 08"  10m 33.7s
    3 Dec noon  16h 35m 13.9s  S22deg 02' 07"  10m 10.5s
    
    Moon
                      RA
    2 Dec midnight 127deg 24'  20deg 05'
    3 Dec noon     133deg 54'  17deg 50'
    3 Dec midnight 140deg 08'  15deg 25'
    
    Lunar distances.
                    Aldebaran West   Regulus East    Sun East
    2 Dec midnight   58deg 00' 46"  22deg 19' 53"
          XV hrs     59deg 37' 27"  20deg 41' 16"
       XVIII hrs     61deg 13' 48"  19deg 03' 06"
         XXI hrs     62deg 49' 50"  17deg 25' 23"  120deg 36' 21"
    3 Dec  noon      64deg 25' 31"  15deg 48' 08"  119deg 06' 46"
         III hrs     66deg 00' 52"                 117deg 37' 33"
    
    No doubt you're aware that EOT (Equation of Time) was then defined in the
    opposite way than we do it now.
    
    If there's anything else that anyone would find useful, I will note it down
    at my next visit.
    
    George.
