    Re: Tides by bearing of the moon
    From: Dave Walden
    Date: 2009 Apr 8, 11:24 -0700

    A quick, but I hope correct, calculation for the next 14 high tides with the 
    moon above the horizon at New London, CT, shows the average azimuth of the 
    moon is 135.4 deg with standard deviation of 3.5 deg (using 6 minute steps).  
    The average LHA is 315.4 with SD=4.6.
    
    As a check, for Frank's low tide (15 in this case), average az=232.4, w/ 
    SD=7.4.  Average LHA, as he says, is 52.9 w/ SD of 1.9.
    
    (using NOAA tide predictions and xEphem moon positions)
