【 摘 要 】

Tutulemma which stands for tutulma (eclipse) and analemma is a Turkish name to describe analemma which contains solar eclipse. The photographs of analemma which looks like a figure 8 pattern of the solar path in the sky throughout a year is very common. However, this observation is rarely done in low latitude countries, especially tutulemma's plot. Related to the eclipse event on 9 March 2016, we built the first tutulemma in Indonesia which cointains partial solar eclipse observed from the rooftop of LAPAN Bandung office. The purpose of this endeavor is also to understand how the sun moves in one year, particularly at low latitude region based on observation data. We took the picture of the Sun every week at the same time of the day (the time of the eclipse). In this observation, we used a tripod and DSLR camera with a variable ND filter to take the data. To obtain the pattern, the weekly data were combined by image stacking using the same foreground. Finally, we got a figure 8 shaped pattern tutulemma which a bit different from high latitude country ones.
