Analemma

The sun was exposed at the same time of day - 8:30 am - on 37 different days for one year. The figure 8 analemma is due to the sun’s north-south seasonal shift. The photographer, Frank Zullo, was careful to space out the shots so the suns wouldn't overlap. Here he explains how to photograph the analemma and much more.

I found the photo through landingaday.wordpress.com - this blogger has been tracking towns and watersheds since November 2008, using his computer to generate a random latitude and longitude in the USA. He looks for information and photos of the town and area - fascinating!

what a great picture! obviously the 37 days didn't include the switch from daylight time to standard time

So is the International Date Line an analemma, then? It looks much the same as the multi-sun photo -- at least that's how it looked in books when I was a kid, over 50 years ago!
