equinox

The intersection of the ecliptic (apparent path of the sun) with the celestial equator

The point at which the ecliptic intersects the celestial equator Days and nights are most nearly equal in duration In the Northern Hemisphere, the vernal equinox falls on or about March 20 and the autumnal equinox on or about September 22

The time of the year when the declination of the sun is 0 degrees On these days, i e March 21st and September 21st the days and nights are of equal length

{i} either of two times in a year when the sun crosses the celestial equator; either of the two points at which the sun's path intersects with the celestial equator

(astronomy) either of the two celestial points at which the celestial equator intersects the ecliptic

An equinox is defined as being when the sun passes through the celestial equator, ie it's declination is 0; The vernal equinox, in northern spring, is when the sun moves from -ve dec to +ve dec, and the autumnal equinox the opposite Due to precession, the point where the vernal equinox occurs, move by approximately 50 seconds of arc per year F Top G

The instant when the sun crosses the celestial equator on its path around the ecliptic Fall equinox occurs on September 21 and spring equinox on March 21, although the times vary slightly from year to year because our calendar has leap years

at the equinox the Sun is over the equator, at this time of year the night and day are of the same length throughout the world There are two equinoxes one in the spring (Vernal) and one in the autumn on or about 21st March and 22nd September respectively

literally "equal night", a day when the number of hours of daylight equals the number of hours of night The vernal equinox, usually March 21, signals the onset of Spring, while the autumnal equinox, usually September 21, signals the onset of Autumn

the date when the sun is directly overhead at the equator (0° latitude) On this day, at all places on the globe, night and day are of equal length (12 hours each) The spring or vernal equinox (for the northern hemisphere) occurs on about March 21 The fall or autumnal equinox (for the northern heisphere) occurs on or about September 23 See also solstice

either of the two days when the periods of daylight and darkness are of equal length The vernal equinox is usually March 21; the autumnal equinox is usually September 23 F

These points are defined on the celestial sphere as those at which the ecliptic crosses the celestial equator The equinoxes are known as the autumnal and vernal (spring) equinoxes The sun reaches the autumnal equinox at the beginning of autumn and the vernal equinox at the beginning of spring The vernal equinox is used to define the point from which right ascension is measured Halfway between the equinoxes lie the solstices

The two points at which the Sun crosses the celestial equator in its yearly path in the sky The equinoxes occur on or near March 21 and September 22 The equinoxes signal the start of the Spring and Autumn seasons

(sol) Either of two times of year when the sun passes over the celestial equator and when the length of day and night are almost equal F - equinoxe S - equinoccio

the two points where the ecliptic intersects the celestial equator; when the Sun appears on the celestial equator

point on the sky where the ecliptic and the celestial equator intercept When the Sun is at the equinox point, it is on the celestial equator and we have 12 hours of daylight Vernal (spring) equinox: March 21; autumnal equinox: September 22

is the time of year when the sun is overhead the equator and day and night are equal Spring equinox is on about March 20 and fall equinox is on about September 22

the time when the sun crosses the earth's equator, making night and day of approximately equal length all over the earth and occurring about March 21 (the spring or vernal equinox) and September 22 (autumnal equinox)

The time when the sun enters one of the equinoctial points, that is, about March 21 and September 22

This is the time when the Sun crosses the celestial equator There are two equinoxes; Vernal (Spring), around March 21st and Autumnal (Autumn) around September 23rd On these dates, day and night are equal Actual dates and times vary due to the Earth's precession
