    Re: A Complete Navigation Log: Thoughts on What Might Be Included
    From: Jeremy C
    Date: 2009 Feb 15, 12:45 -0800

    For a navigational day I will do the following:
    
    Precalculate Sunrise and Twilight, calculate moonrise/set if
    applicable.
    precalcuate the six stars from HO 249 Vol 1 (I can see the planets and
    moon so don't bother including those)
    Shoot a round of AM stars
    Shoot an amplitude if available
    
    AM sunlines (every hour if possible) crossed with moonlines and/or
    daylight planet fixes
    get an AM azimuth
    
    LAN usually crossed with one or more Sun lines advanced/retarded to
    1200L.  Determine day's run with noon to noon via mercator sailing.
    
    PM sunlines crossed with LAN advanced and/or PM sunlines
    PM azimuth
    
    precalculate sunset and PM twilight
    precalculate PM stars (same rules as AM stars)
    shoot PM stars and PM amplitude if possible
    
    If you want to get daring, shooting a lunar in there is always good.
