Sun Path Charts

[@glovernursery]

Great explanation! Sometimes we have to explain to clients why the tree they planted in Spring isn't shading the same place in the Summer. This helps!

Awesome video thank you ! There are two options I like to check ...."Crop azimuth axis to fit plotted data" and "Crop elevation axis to fit plotted data" It makes the sun path chart easier to use. I guess that would get weird if you are closer to the equator but an option worth playing with.

Very informative. Well-oriented and concise. Just about everything I need to know. Thank you so much :)

[@markawbolton]

Great explanation. Good pace too - might be a little slow for some but the stepwise elucidation helps it sink in for me.

This is awesome, just what I wanted. Thanks!

Brilliant (and funny), thanks Jim.

Thankyou now I understand how to read sun path diagram in tropic

[@GabrieleAndrades]

Great explanation, easy to follow even for me whom speaks english as a Second language

Oh God...every lecture I've heard starts off soundly until it gets to the point where they almost vomit at wanting to say that the Sun travels a 360° path. The math and the terminology all keep pointing to the fact that we live on a plane and not a globe. As for the twelve lines you mentioned good sir it sounds to me as if there are six points through which the Sun, Moon and stars travel through twice a year for a total of 12 Solar months...good Lord...this means that the days of the year correlate directly with the number of degrees the sun travels...and...that means the four times of the year (i.e. the equinoxes and the solstices) are intercalated to...holy moly... *52 Weeks × 7 Days = 364 Days* And with the math on this sun path chart/diagram means...we only have 364 Days per year and not what we've been taught...

Hey there Jim, Thank you for this, and Happy New Year! I'm over at the University of Oregon's website. It says; "[Important: south latitude and west longitude are given in negative degrees. Minutes and seconds must be converted to decimal degrees; e.g., 30 min. = 0.5 deg.]" I'm not sure that I understand... I don't have a negative south latitude, but I do have a negative west longitude of .72 tagged on at the end. I'm not sure I understand the conversion to decimal part... .72 is just .72%? Can you please tell me how to convert the negative degrees? Maybe this is just a brain fart, but I used to know this stuff when I had a boat back in my 20s. Now I'm 60 and can't remember how that works. Thanks so much.

[@bigbadtech]

One minute is 1/60th of a degree and a second is 1/60 of a minute. Example: 30 minutes 30 seconds is .5 degrees (30/60) plus .083 (30/60/60) degrees for a total of .508 degrees. Honestly for sun path charts a user is most likely fine neglecting both minutes and seconds.

[@momzilla9491]

@@bigbadtech Wow, this is great news. Thanks for helping so long after you posted this video! So I can ignore the minutes and seconds for long and lat. However, I don't think that I can ignore these if, I am also trying to show altitude? Again, thanks so very much!

thanks!

Still I didn't get that irregularity in the chart for maxico city?

[@bigbadtech]

Think of the horizontal axis of the sun chart as the angular position of a cylinder and the observer is inside the cylinder facing south. In regions near the equator the sun will be in the northern half of the sky (ie: behind the observer) at certain times of the year.
