Analemma

Came across an intriguing link on the British Cartographic Society web page just now. I was surfing around on the BCS site and enjoying the interesting links in the Curators Toolbox. There are a whole host of geo type sites listed. Not all the links work but it doesn't claim to be exhaustive nor 100% up-to-date.

I was fascinated by the link titled 'analemma'. I either haven't come across this before or when it was mentioned in my geodesy lectures at university I nodded off. Anyway, an analemma is the figure of 8 path that the sun makes in the sky over the course of the year. That's assuming you lie flat on your back for a whole year watching it.
