365 Sunset, a year of Tenerife sunsets captured with time-lapse

Watch more with these video collections:

“With a camera located at the Izaña Atmospheric Research Center, the apparent movement of the Sun over the western horizon was captured with the passing of the seasons… The final video shows the equinoxes and solstices, as well as the movement from the Sun in 365 days along the horizon line.”

Watch as the position of the sun moves northward or southward along the horizon over the course of the year due to the tilt of the Earth’s axis. This lovely observational video was made in 2020 by the TeideLab project: Aemet Izaña, Teleférico del Teide and Daniel López.

More information from the Griffith Observatory:

“At the start of spring and fall (the equinoxes), the Sun rises due east and sets due west. On the summer solstice (around June 21), the Sun rises and sets at its most northerly points along the horizon. On the winter solstice (around December 21), the Sun rises and sets at its most southerly points.”

December solstice
