Tracing the Sun from Solstice to Solstice

 Today, December 21st, would have been my mother’s 99th birthday and of lesser import it is also the Solstice, the first day of winter in the north and summer in the south. To celebrate, watch this amazing timelapse video tracing the Sun’s apparent movement over an entire year from Hungary.

Over the course of a year, a fixed video camera captured an image every minute. A total of 116,000 exposures follow the Sun’s position across the field of view, starting from the 2015 June 21 solstice through the 2016 June 20 solstice. The intervening 2015 December 22 solstice is at the bottom of the frame.

The timelapse sequences constructed show the Sun’s movement over one day to begin with, followed by traces of the Sun’s position during the days of one year, solstice to solstice. Gaps in the daily curves are due to cloud cover. The video ends with stunning animation sequences of analemmas, those figure-8 curves you get by photographing the Sun at the same time each day throughout a year, stepping across planet Earth’s sky.
