Dear Greg, 

Thank you for your reply.  

If my longitude is 97 degrees 36.0' W, what local time would the transit occur 
given that Daylight Saving Time is in effect, please?

Steve


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?
