Sun's Daily Journey: Tracing its Path Across the Sky

An image capturing the path of the Sun across the sky in Germany between the summer solstice and winter solstice in 2018 has been featured in a competition by the International Astronomical Union's Office of Education. The image, created by Frank Niessen using a pinhole camera made from a coffee can, combines images taken at different times of day over six months, with each curve representing the Sun's path on a specific day. Gaps in the image indicate cloudy days.
