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 46.2° N, 100.7° E, and accurate to about a minute.
