Re: [Phys-L] sun path diagram

 While Gaisma offers more different bits of information SunCalc offers some similar information overlaid on a street map. For example,

https://www.suncalc.org/#/37.8011,-122.3987,16/2022.08.16/13:11/2/3
It can help you discover things like Manhattanhenge where the setting sun aligns with the street grid in Manhattan. https://www.suncalc.org/#/40.7586,-73.9814,18/2023.05.29/20:11/2/3 ; Sadly, that never happens in San Francisco. Although we have Eye of Sauron Day where the sun shines directly between the spires of a downtown building https://www.suncalc.org/#/37.7926,-122.4005,19/2023.05.17/13:58/212/3 sometimes called the Tweezer Building.

 Hi --

Maybe everybody but me already knows about this, but I
only recently ran across this "sun path diagram".

  https://av8n.com/physics/img48/sun-path.jpg

It's a nifty bit of data visualization.
I like that sort of thing.

This showed up in a gardening discussion group, in the
context of how much direct sunlight a plant will receive
on the north side of a wall.

You can create a diagram customized for you favorite
location:
