  If one asked some friends where on the horizon they should expect to see the
sunrise, half of the answers would be "in the east". Of course, something
analogous would happen with the sunset and the west. However, sunrise and
sunset virtually never occur at these cardinal points. In fact, those answers
correctly describe observations only during the equinoxes, when either autumn
or spring begin. Once we recall this, the next natural question to ask
ourselves is: how far from the east (or from the west) the rising (or setting)
Sun is located for a given latitude of the observer and for a given day of the
year. In this paper we supply some simple tools to easily visualize the angular
(southward or northward) departure of the rising and setting Sun on the horizon
from the east-west direction in a pictorial way, without the need of
mathematics. These tools have proven a valuable resource in teaching
introductory physics and astronomy courses.
