A good Analemma Calculator (online)?

[Nathan]

Hi,

I'm new to astronomy but I have learnt something interesting that could be of use to me for a project at University.

Basically I want to be able to view the analemma plotted online for a site that I have the co-ordinates for.

I've searched online already but I either get way too confused with all the figures or the website no longer works.

Does anybody know where I can calculate the analemma online for free?

Thank You

I have no idea whether they will be any good for you but I hope so. Welcome to sgl by the way

Yes I tired that but all I get is some figures which I don't understand.

Thank You

How exact do you need this? I can get Starry Night Pro to make a movie easily, but probably need Xephem to make a better job. Incidentally the sun describes a bowling pin shape from 57N 2E over a year...

It doesn't need to be exact. It's used for graphical purpose only (using it in contemporary Architecture at University) so it's not going to be checked, I just wanted to understand it before putting forward my concept (we all know the sun is related to the orientation of sacred buildings...)

I've attached other co-ordinates if needed. All I want is the positioning of the dots which represent the sun, I have already got the shape but if your software can also produce theta, it's good to know if I'm right!

Thank You

I have downloaded Stellarium but I'm not sure how I view or create the analemma. I've entered the site co-ordinates but from there I'm lost! Does anybody use stellarium that may be able to assist me with setting it up please?

Just for giggles I've programmed Starry Night Pro to do this - exporting a HD movie and have
