No, not that kind of Equinox, the Astronomical one. We have a few days to plan our strategy.
September 23rd, the sun will rise due east and set due west regardless of where you are on earth — shadows, likewise, will align due west at sunrise, and due east at sunset.
Find a clear view of the horizon on a quiet east-west street or road and photograph your bicycle as the sun rises or sets. Its shadow will fall due west or east depending on which you choose, and the sun will be exactly in the middle of the road.
(This will be a one day challenge (obviously) — but it would be neat to do the same photo at the Winter and Summer Solstices.)
At the Winter Solstice, the sun will be well south of the road, and at the Summer Solstice, the sun will be well north of the road. (Reverse that for the Southern Hemisphere.)
If you want to include a Chevy Equinox, thats fine too. 😉
The analemma shows the location of the direct ray of the sun and the amount of error of a sundial.
Here you can see the direct ray of the sun is approximately at 3 degrees N Latitude 9/14/18 and creeping south.
