The following panoramic time lapse video was taken just before sunset using my GoPro HERO4 Black action camera mounted on a "360TL" rotating timer. The camera was set for "Video" mode / "Time Lapse Video" submode, using a resolution of 4K and an interval of two (2) seconds.
22 November 2025. Facing southwest.
Sunset occurred at 4:50 pm EST on 22 November 2025, according to the Table of Sunrise/Sunset, Moonrise/Moonset, or Twilight Times for an Entire Year, Astronomical Applications Department, U.S. Naval Observatory.
Motions of the Sun Simulator
Two motions -- the rotation of the Earth around its axis, and the revolution of the Earth around the Sun -- cause daily- and annual cycles in the Sun's apparent path across the sky. Every day, the Sun appears to move across the sky from east to west as the Earth rotates counterclockwise. And from day-to-day, the apparent path of the Sun across the sky changes slowly due to the tilt of the Earth's axis and the Earth's revolution around the Sun.
The Motions of the Sun Simulator can be used for open-ended exploration of daily and annual motions of the Sun. The following screenshot shows the simulator configured for 22 November at 12 noon. Notice the Sun rises along the southeastern horizon and sets along the southwestern horizon.
