Sun Photograph, Year Long Exposure

[marcus_k.]

I remember seeing in the photo.net forums awhile ago, a discussion

about a year long shot of one specific spot in the sky with a single

exposure taken about once a month of the sun. So at the end the photo

showed the path of the sun as it moved throughout the year.

 

I've done a bunch of searches and can't seem to find it here or on any

other site. Does this sound familiar to anyone? Any example of the

photos?

Try doing a google search for 'analemma'

The figure the sun makes over a year is called an "analemma". A

google search turns up a number of hits, including <a href="http://antwrp.gsfc.nasa.gov/apod/ap020709.html">this one</a> and

<a href="http://antwrp.gsfc.nasa.gov/apod/ap030320.html">this one</a>.

Not to be a smartass, but... you do mean the path of the earth as it revolved around the sun throughout the year, right??

wait a minute, are you saying the EARTH rotates around the SUN!? Are you sure, that seems a little far fetched. Next thing I know you'll be saying the earth is not flat or something crazy. :)

 

Thanks for the answers, analemma is exactly what I was looking for!

"are you saying the EARTH rotates around the SUN!? "

 

The earth orbits the sun, and rotates around its own axis. ;)

 

BTW, good topic and I like the cool photos of the year long cycle.
