The beginning of the astronomical night is the moment when the sun drops below the horizon below 18 degrees.
The end of the astronomical night is the moment when the sun is less than 18 degrees below the horizon.
Distance from Earth to Sun — the distance from the center of Earth to the center of Sun.
Astronomical twilight — the period of time during which the sun is below the horizon, and the natural illumination on Earth is provided by the reflection of sunlight from the upper atmosphere. The interval of the angle of the sun under the horizon from 12 ° to 18 °. Usually, astronomers can already observe celestial bodies at this time.
Astronomical night does not occur on this date - the sun does not fall below 18 ° from the horizon (or does not rise, in the case of a polar night).
Sunrise Time — the moment when the upper edge of the solar disk becomes visible on the horizon. This parameter depends on many factors, such as the location and height of the observer above sea level, the presence of obstacles on the horizon (mountains, houses), atmospheric refraction, and others.
The sun does not rise on this date (the sun does not rise above the horizon)
The sun does not set on this date (the sun does not drop below the horizon)
Sunset Time — is the point in time when the solar disk is completely hidden behind the horizon line. This parameter, like sunrise, depends on the latitude and longitude of the observer, so it is important to indicate your exact location.
Astronomical night does not occur on this date - the sun does not fall below 18 ° from the horizon (or does not rise, in the case of a polar night).
Astronomical twilight — the period of time during which the sun is below the horizon, and the natural illumination on Earth is provided by the reflection of sunlight from the upper atmosphere. The interval of the angle of the sun under the horizon from 12 ° to 18 °. Usually, astronomers can already observe celestial bodies at this time.
Nadir (Antizenith) — is a point in the celestial sphere located under the horizon, opposite the zenith. In relation to the sun, this is the lowest point reached by the sun in its orbit, relative to the observer.
Julian date — is an astronomical method of measuring time, which counts the number of days that have passed since Monday noon, January 1, 4713 BC Julian calendar (or from November 24, 4713 Gregorian calendar, which is the same).
Local time is determined for a specific place on Earth, depending on geographic longitude. Usually, it is the same for all settlements located on the same meridian.
Universal Time (or Coordinated Universal Time, UTC) is an atomic time scale that approximates the UT1 standard (calculated in proportion to the angle of rotation of the Earth relative to the international celestial coordinate system ICRS), on which time zone time is based. UTC witness synchronously with international atomic time.
Daylight hours — the time interval between sunrise and sunset. During this period, at least part of the solar disk should be above the horizon.
Sunrise Direction — the angle counted counterclockwise between the direction to the south and the sunrise point is always negative.
Sunset Direction — the angle counted in a clockwise direction between the direction south and the point of sunset. Is always positive.
The vernal equinox — is an astronomical phenomenon when the sun, in its visible motion along the ecliptic, crosses the celestial equator. In other words, on the day of the vernal equinox, day is almost equal to night, while the length of daylight continues to grow.
The Summer Solstice — is the moment when the Sun, in its movement along the ecliptic, enters its northernmost point in the northern hemisphere, or the southernmost point in the southern hemisphere. The summer solstice is the longest daylight hours of the year (and the shortest night).
Autumnal equinox — is an astronomical phenomenon, when the Sun in its visible motion along the ecliptic crosses the celestial equator. In other words, on the day of the autumnal equinox, the day is almost equal to night, while the duration of daylight hours decreases with each subsequent day.
Winter Solstice — is the day of the year when the Sun passes through the southernmost point of the ecliptic in the northern hemisphere (or through the northernmost point in the southern hemisphere). The winter solstice is the shortest daylight and the longest night.
Blue hour — a period of time shortly before sunrise (or after sunset), when the sky turns intense blue, due to which saturated blue shades begin to prevail in natural light.
Golden hour — the period of time when the sun is close to the horizon (immediately after sunrise or shortly before sunset), while natural light gives a soft and rich golden color.
Blue hour — a period of time shortly before sunrise (or after sunset), when the sky turns intense blue, due to which saturated blue shades begin to prevail in natural light.
Golden hour — the period of time when the sun is close to the horizon (immediately after sunrise or shortly before sunset), while natural light gives a soft and rich golden color.
The elevation of the sun — is the angle between the horizon and the position of the Sun in the sky at a certain point in time, measured in degrees. If the sun is below the horizon, the height becomes negative. Measured perpendicularly horizon plane.
Hour angle — the angle between the south point and the position of the sun in the sky, measured along the horizon in a clockwise direction.
