All times are local time for London. They take into account refraction. Dates are based on the Gregorian calendar. Today is highlighted.

Accounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.

Near the equator, the variation of the time of sunrise is mainly governed by the variation of the equation of time. See here for the sunrise chart of a different location The stage of sunrise known as false sunrise actually occurs before the Sun truly reaches the horizon because Earth's atmosphere refracts the Sun's image. At the horizon, the average amount of refraction is 34 arcminutes, though this amount varies based on atmospheric conditions.

Dates are based on the Gregorian calendar. Today is highlighted. In late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.

Twilight, the period in the morning during which the sky is brightening, but the Sun is not yet visible. The beginning of morning twilight is called astronomical dawn.All times are local time for Sydney. Time is adjusted for DST when applicable. They take into account refraction.

Measurement [ edit ] Angle with respect to horizon [ edit ] This diagram of the Sun at sunrise (or sunset) shows the effects of atmospheric refraction Commodities & Futures: Futures prices are delayed at least 10 minutes as per exchange requirements. Change value during the period between open outcry settle and the commencement of the next day's trading is calculated as the difference between the last trade and the prior day's settle. Change value during other periods is calculated as the difference between the last trade and the most recent settle.
