Baby Let’s Fly Away

sunset flight

F/9.0, 1/1250, ISO 100.

A day without sunshine is like, well, night.

Interesting Fact: Neglecting atmospheric refraction and the Sun’s non-zero size, whenever and wherever sunset occurs, it is always in the northwest quadrant from the March equinox to the September equinox, and in the southwest quadrant from the September equinox to the March equinox. Sunsets occur almost exactly due west on the equinoxes for all viewers on Earth. Exact calculations of the azimuths of sunset on other dates are complex, but they can be estimated with reasonable accuracy by using the analemma. ( )
