Tutulemma: Solar #Eclipse Analemma

Capturing the Sun's path at the same time daily creates an analemma, a figure-8 pattern. On Winter Solstice, it's at its lowest point. Analemmas vary by latitude and timing. A 'Tutulemma' includes a solar eclipse, like this composite from Turkey since 2005, featuring the 2006 eclipse and Venus.
