We saw the total solar eclipse from ancient Side (pronounced C-day) on the south coast of Turkey in 2006 so this picture has extra meaning for us.

Tutulemma: Solar Eclipse Analemma

If you went outside at exactly the same time every day and took a picture that included the Sun, how would the Sun appear to move? With great planning (http://en.wikipedia.org/wiki/Image:Train_wreck_at_Montparnasse_1 895.jpg) and effort, such a series of images can be taken. The figure-8 path the Sun follows over the course of a year (http://www.uwm.edu/%7Ekahl/Images/Weather/Other/analemma.html) is called an analemma (http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search?analemma). With even greater planning and effort, the series can include a total eclipse of the Sun (http://antwrp.gsfc.nasa.gov/apod/ap050407.html) as one of the images. Pictured is such a total solar eclipse analemma (http://en.wikipedia.org/wiki/Analemma) or Tutulemma - a term coined by the photographers based on the Turkish word for eclipse. The composite image sequence was recorded from Turkey (http://en.wikipedia.org/wiki/Turkey) starting in 2005. The base image for the sequence is from the total phase (http://antwrp.gsfc.nasa.gov/apod/ap060404.html) of a solar eclipse as viewed from Side (http://en.wikipedia.org/wiki/Side%2C_Turkey), Turkey on 2006 March 29. Venus was also visible during totality, toward the lower right.

Here is the local Analemma at latitude 29 south showing the Sun's position weekly at 8am looking east.
The Sun moves rapidly at this time of the year. The map was generated by SkyMapPro.
