Sunrise or sunup is the moment when the upper rim of the Sun appears on the horizon in the morning. Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame ; this apparent motion caused many cultures to have mythologies and religions built around the geocentric model , which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century. Architect Buckminster Fuller proposed the terms "sunsight" and "sunclipse" to better represent the heliocentric model, though the terms have not entered into common language. Astronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon. 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.

Figure 7. The daily or diurnal paths of the Sun during the solstices 21 December and 21 June and the equinoxes 21 March and 21 September as seen by an observer at the equator. Solid lines are daytime, dashed lines are night-time. At all seasons on the equator, the daily paths of the Sun are divided equally above and below the horizon. The same information shown in Figure 7 is presented in Figure 7a, below, in the form of a polar plot of the position of the Sun in the coordinates of the azimuth and altitude of the Sun as seen by an observer at that latitude. Figure 8 and 8a show the apparent paths of the Sun as seen from Hawai'i, the southernmost State of the United States, 21 degrees north of the equator. The paths are all parallel to each other, but are slanting at 21 degrees to the horizon. It will also be noticed that the horizon divides the total path of the Sun into equal periods only on the first days of spring and fall, i. In summer, the portion of the Sun's path above the horizon is much greater than the night portion, and the reverse is true in the winter. This illustrates the geographical effect , which depends on the observer's latitude.

Where Does the Sun Rise and Set? Most people know that the Sun "rises in the east and sets in the west". However, most people don't realize that is a generalization. Actually, the Sun only rises due east and sets due west on 2 days of the year -- the spring and fall equinoxes! On other days, the Sun rises either north or south of "due east" and sets north or south of "due west. At the summer solstice, the Sun rises as far to the northeast as it ever does, and sets as far to the northwest. Every day after that, the Sun rises a tiny bit further south.

Find sunrise and sunset times for any location on planet Earth. Enter latitude and longitude and select the time zone for your location. This sunrise sunset calculator finds the time of day for sunrise, sunset, dawn and dusk given latitude, longitude and UTC offset. Learn more about the different types of twilight below. Enter degrees and minutes as whole numbers, or degrees and minutes as a decimal number. If you enter degrees as a decimal number you should leave the minutes field blank. If your location is west of the Prime Meridian you should enter a negative longitude. If your location is south of the equator you should enter a negative latitude.

What time the sun rises

Depending on the time of the year and when you wake up , you may witness the beautiful colors of sunrise: learn how to calculate the sunrise hour , and never miss the first light of the day Sunrise is, by definition, the moment of the day when the Sun crosses the eastern horizon and the day begins. It's not that easy, however, since sunrise is not an on-off phenomenon. First, let's define sunrise: the sunrise time we will calculate in this tool is the time at which the upper edge of the solar disk touches the horizon.

Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly. Sunrise or sunup is the moment when the upper rim of the Sun appears on the horizon in the morning. Tools Tools. Figure 8 and 8a show the apparent paths of the Sun as seen from Hawai'i, the southernmost State of the United States, 21 degrees north of the equator. Archived from the original on August 22, Where Does the Sun Rise and Set? 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. Road Town. Sunni - Worldwide distribution Distribution and regional allocation of the religion: Sunni. The analemma can be used to make approximate predictions of the time of sunrise. New Delhi.

Sunrise or sunup is the moment when the upper rim of the Sun appears on the horizon in the morning. Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear.

Neglecting the effects of refraction and the Sun's non-zero size, whenever sunrise occurs, in temperate regions it is always in the northeast quadrant from the March equinox to the September equinox and in the southeast quadrant from the September equinox to the March equinox. Renewable Energy , , The paths are all parallel to each other, but are slanting at 21 degrees to the horizon. United Kingdom. Burkina Faso. Ivory Coast. French Polynesia. Andorra la Vella.
