Explanation:
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
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.
This coming Tuesday, the
Winter Solstice
day in Earth's northern hemisphere, the Sun will be 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 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.
