    en.wikipedia.org/wiki/Sunrise

    Sunrise seen over the Atlantic Ocean through cirrus clouds on the Jersey Shore at Spring Lake, New Jersey, U.S. Sunrise (or sunup) is the moment when the upper rim of the Sun appears on the horizon in the morning, [1] at the start of the Sun path. The term can also refer to the entire process of the solar disk crossing the horizon.

  3. Sunrise equation - Wikipedia

    en.wikipedia.org/wiki/Sunrise_equation

    The above relation implies that on the same day, the lengths of daytime from sunrise to sunset at and sum to 24 hours if =, and this also applies to regions where polar days and polar nights occur. This further suggests that the global average of length of daytime on any given day is 12 hours without considering the effect of atmospheric ...

  4. Sunset - Wikipedia

    en.wikipedia.org/wiki/Sunset

    Calculate the sunset time, which is the solar noon time plus the sunset hour angle in degree divided by 15; Use the sunset time as input to the solar geometry routine to get the solar azimuth angle at sunset. An interesting feature in the figure on the right is apparent hemispheric symmetry in regions where daily sunrise and sunset actually occur.

  5. Sunrise, Sunset - Wikipedia

  6. Sun path - Wikipedia

    en.wikipedia.org/wiki/Sun_path

    Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.

    Sunset and Sunrise (Arabic: غروب وشروق, romanized: Ghoroub wa Shorouq), 1970 Egyptian political film; Sunset Sunrise (Japanese: 陽は沈み陽は昇る, romanized: Hi wa shizumi hi wa noboru), a 1973 film by Koreyoshi Kurahara

  8. Analemma - Wikipedia

    en.wikipedia.org/wiki/Analemma

    The point where the Sun is at sunrise or sunset represents the direction of sunrise or sunset. Simply measuring the distance along the horizon between these points, in angular terms (comparing it with the length of the analemma, as described above), gives the angle between due east or west and the direction of sunrise or sunset.

  9. Solar zenith angle - Wikipedia

    en.wikipedia.org/wiki/Solar_zenith_angle

    Sunset and sunrise occur (approximately) when the zenith angle is 90°, where the hour angle h 0 satisfies [2] ⁡ = ⁡ ⁡. Precise times of sunset and sunrise occur when the upper limb of the Sun appears, as refracted by the atmosphere, to be on the horizon.
