### Analemma Observed in Taipei, Taiwan

December 10, 2021

Photographer: Meiying Lee
Summary Authors: Meiying Lee; Jim Foster
This analemma was captured in Taipei, Taiwan, from September 22, 2020 to September 23, 2021. All images were shot at 4:30 p.m. local time, using a solar filter, from the same viewing platform on a hillside east of Taipei. Each white dot represents the position of the Sun. The summer solstice is at upper right, and the winter solstice at lower left. Note that because of Earth's 23.5-degree axial tilt, the figure 8 appears stretched out. Also, if Earth had a circular orbit, both lobes of this figure 8 would be the same size.

Due to heavy winter and spring rains and frequent summer afternoon thunderstorms, out of 46 trips to this location only 30 images were usable, resulting in uneven gaps in the analemma. Therefore, this analemma also documents the afternoon weather in Taipei during the course of these 12-months. Note that the tall building in the foreground is Taipei 101 (1,667 ft or 508 m).
