Explanation: If you went outside at exactly the
same time every day and took a picture that included the Sun, how would the
Sun's position change? With great planning and effort, such a series of images
can be taken. The figure-8 path the Sun follows over the course of a year is
called an analemma. Yesterday, the Winter Solstice day in Earth's northern
hemisphere, the Sun appeared at the bottom of the analemma. Analemmas created
from different latitudes would appear at least slightly different, as well as
analemmas created at a different time each day. With even greater planning and
effort, the series can include a total eclipse of the Sun as one of the images.
Pictured is such a total solar eclipse analemma or Tutulemma - a term coined by
the photographers based on the Turkish word for eclipse. The above composite
image sequence was recorded from Turkey starting in 2005. The base image for
the sequence is from the total phase of a solar eclipse as viewed from Side,
Turkey on 2006 March 29. Venus was also visible during totality, toward the
lower right.
