LATITUDE GNOMON AND QUADRANT FOR THE WHOLE YEAR

Sakari Ekko
"EAAE Summerschools" Working Group (Finland)

Abstract

In this workshop, we examine the correlation between our latitude and the altitude of the Sun at noon at different dates. Using this correlation, we build a quadrant with an adjustable scale for finding our latitude by observing the noon altitude of the Sun. A Viking gnomon for the same purpose is demonstrated. The students work with the concepts of declination, altitude, seasons and latitude.
