HOW IT WORKS TAKING A NOON SIGHT

To take a sextant noon sight you first have to figure out when the sun will pass over your meridian.

- 

It is good enough to work it out to the closest minute. Start by taking a sight of the sun a couple of minutes before the calculated meridian passage. Remember, it's important that you don't make any adjustments to the sextant as you do this. Wait a minute before taking another shot. You'll notice that the sun will now be a little bit higher in the sky. Keep repeating this procedure until you can see that the sun no longer rises. At that point you will have taken a noon sight.
