Explanation:
Does the Sun set in the same direction every day?
No, the direction of sunset depends on the time of the year.
Although the Sun always sets approximately toward the west, on an
equinox
like today the Sun sets directly
toward the west.
After today's September equinox, the Sun will set
increasingly toward the southwest, reaching its maximum displacement at the December
solstice.
Before today's September equinox,
the Sun
had set toward the northwest, reaching its maximum displacement at the June solstice.
The featured time-lapse image shows seven
bands of the Sun
setting one day each month from 2019 December through 2020 June.
These image sequences were taken from
Alberta,
Canada --
well north of the Earth's equator -- and feature the city of
Edmonton in the foreground.
The middle band shows the Sun
setting during the last equinox -- in March.
From this location, the Sun will set along this same
equinox band
again today.
