Description

Known as ANALEMMA, this unique photo-composite is taken over one year and depicts the motion of the Sun in the sky at the same time of the day every two weeks or so. But this particular analemma is special, with an annular eclipse right on top of the figure of 8. The solstice eclipse of 21 June in India. It’s a Tutulemma! The term tutulemma was first used for this 2006 analemma with a total solar eclipse by another TWAN member Tunc Tezel in Turkey.

This project to create the Indian Solar Eclipse Analemma was started on 10 February 2020. All the Sun images were shot from home at Gurugram, Haryana, India. The camera was kept facing the same direction (south) and at the same altitude above horizon (45°) for each shot and Sun was imaged each day the sky was clear of clouds. The image of the annular eclipse was clicked at Sirsa. The effect of the difference between the longitudes of Gurugram and Sirsa was compensated by clicking the Gurugram images earlier than the middle of the annular eclipse time so that the position in the sky remains the same. The background image is of Chilla Sahib Gurudwara at Sirsa, using exact same direction (south) and altitude above horizon 43.8°, since Sirsa is 1.2° North of Gurugram.
