Drag the large red pin with the dot to the desired location and enter the date and time at which to calculate the sun position. Location: Latitude: Latitude - An angular measurement of north-south location on Earth's surface. Longitude: Longitude - An angular measurement of east-west location on Earth's surface.
Time Zone: time zone and UTC offset are automatically determined when possible based on the given location and date. Once the location has been set, the user may manually override the time zone or UTC offset by selecting them here. The user can manually override this value by entering it here after location, time zone and date have been set. Save Location. Equation of Time Equation of time - an astronomical term accounting for changes in the time of solar noon for a given location over the course of a year.
Earth's elliptical orbit and Kepler's law of equal areas in equal times are the culprits behind this phenomenon. Solar Declination Solar Declination - The declination of the sun. The solar declination varies from The variation in solar declination is the astronomical description of the sun going south in the northern hemisphere for the winter. Solar Noon Solar Noon - Defined for a given day for a specific longitude , it is the time when the sun crosses the meridian of the observer's location.
At solar noon, a shadow cast by a vertical pole will point either directly north or directly south, depending on the observer's latitude and the time of year. Apparent Sunrise Apparent Sunrise - Due to atmospheric refraction , sunrise occurs shortly before the sun crosses above the horizon. Light from the sun is bent, or refracted, as it enters earth's atmosphere.
