    Re: Meridian Transit of the Sun and Daily Pages

    Steve,

    I get 11:51 for meridian passage of the Sun on 9/27/2015. This is for standard time. Daylight savings or summer time will be +1 hour 12:51. Then you will have to figure arc to time for your longitude. 1° west of prime meridian is 4 minutes of time later. 1° east is 4 minutes of time sooner. For example if you were in Chicago then the meridian passage would be about 8 minutes sooner plus 1 hour for daylight savings 12:43.  If LAN is being observed with a sextant then there is around 4 minutes either side of meridian passage to mark the observation.

    Dear Navlisters,

     

    How does one determine the meridian passage of the sun using the Nautical Almanac 2015 Commercial Edition, daily pages, specifically referencing the data located on the right hand bottom of the far right hand page for 27 September?

     

    Steve
