I've found some flash animations for the Solar Analemma where I could change parameters such as latitude of observer, and I could see the resulting effect on a 3D image. This is it: http://astro.unl.edu/classaction/animations/coordsmotion/sunmotions.html

But I want more. I also need to be able to change Earth's eccentricity and/or axial tilt and see the corresponding effect on the shape and size of the analemma.

Where can I find something that does this?

  • $\begingroup$ Hi. Idk if such a thing exists (it probably does). The "Equation of Time" is something that does it ... en.wikipedia.org/wiki/… $\endgroup$ – user31179 Dec 14 '19 at 18:33
