A place were I can write...
My simple blog of pictures of travel, friends, activities and the Universe we live in as we go slowly around the Sun.

Sun's position change
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.
