Good to know

  • Sunrise and sunset mark the moment the Sun’s upper edge touches a level horizon, with the air’s usual bending of light allowed for. Hills, buildings and altitude move what you see by a few minutes.
  • Civil, nautical and astronomical twilight end when the Sun is 6°, 12° and 18° below the horizon. Golden hour here is the photographers’ usual definition: the Sun less than 6° above it.
  • Worked out when the page loads from NOAA’s solar equations, for 1.6° N, 18.1° E, and accurate to about a minute.
