Explanation:
On September 18, the setting Sun illuminated both sides of the
steep brick and steel canyon otherwise known as Jasper Avenue in
downtown Edmonton, Alberta, Canada, planet Earth.
The Stonehenge-like alignment is captured from the
middle of the road in
this
daring snapshot.
In Edmonton streets are laid out on a grid almost oriented along the
cardinal directions, so
aligned Edmonton sunsets (and sunrises) occur along
the nearly east-west streets twice a year, close to the Equinox.
In fact, at today's Equinox, the Sun crosses the
celestial
equator at 1421 UT and on this day the Sun will rise due
east and set due west, bringing approximately
equal hours of day and night to denizens of planet Earth.
The September Equinox
marks
the
astronomical beginning of
Fall in the north and spring in the southern hemisphere.
