Declination Table For Survival Use

Sun’s Declination Table constructed for use in survival situations to be used when calculating latitude from the altitude of the midday sun.

Provided by Astro Navigation Demystified (

The following table shows the mean values of the declination of the Sun for each day of the year over the leap year cycle.

The value of each declination is taken to 1 decimal place which is compatible with the expected accuracy of a clinometer reading.
