The intersection of the ecliptic (apparent path of the sun) with the celestial equator
{n} the time when the day and night are equal
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
The time of year when the sun crosses the plane of the Earth's equator, making the length of night equal to that of day This occurs twice a year, once at the beginning of Spring and once at the beginning of Fall (Source: Mintzer, 1992)
the intersection of the ecliptic (apparent path of the sun) with the celestial equator. Vernal Equinox is the intersection that the sun crosses about March 20; autumnal equinox denotes the crossing point about September 23
The time when the sun crosses the plane of the Earth's equator occurring about March 21 and September 22 During the Equinox, the day will have equal number (12) of daylight and nighttime hours
either of two times of the year when the sun crosses the plane of the earth's equator and day and night are of equal length
Either of the two instants during the year when the Sun is directly over the Earth's equator In the spring in the Northern Hemisphere, the vernal equinox occurs around March 21st, and in the fall the autumnal equinox happens around September 21st (although the specific dates vary slightly from year to year ) At the time of the equinoxes, the length of day and night are very nearly equal all over the world In the United States, spring and fall officially begin at the instants of the vernal and autumnal equinoxes, respectively
An equinox is one of the two days in the year when day and night are of equal length. In the Chinese calendar, the Spring Equinox always occurs in the second month. one of the two times in a year when night and day are of equal length (équinoxe, from aequinoctium, from aequi- ( EQUI-) + nox ). Either of two moments in the year when the Sun is exactly above the Equator and day and night are of equal length all over Earth; also, either of two points in the sky where the ecliptic and the celestial equator (see celestial sphere) intersect. The vernal equinox, when spring begins in the Northern Hemisphere, occurs about March 21, when the Sun moves north across the celestial equator. The autumnal equinox falls about September 23, as the Sun crosses the celestial equator going south. See also solstice
The intersection of the ecliptic (apparent path of the sun) with the celestial equator Vernal equinox is the intersection that the sun crosses about March 21; autumnal equinox denotes the crossing point about Sept 21
Two periods when the declination of the sun is at the equator The autumnal equinox occurs on March 21 or 22 The vernal equinox occurs on September 22 or 23
The times when the Sun crosses the celestial equator The vernal equinox, the first day of spring, occurs when the Sun is at the first point of Aries (oh RA, 0o DEC), on about March 23 The autumnal equinox, the first day of fall, occurs when the Sun is at 12h RA, 0o DEC), on about September 23
See Autumnal equinox, Vernal equinox, under Autumnal and Vernal
Time when the sun crosses the geographic equator Day and night are of equal lengths Occurs in March and September
Equinoctial wind or storm
the time of the year (around March 21 and September 23) when the position of the Sun in the sky (following the ecliptic) crosses the celestial equator To a good approximation, the length of the day and night are then equal, and the Sun rises exactly in the east and sets exactly in the west Equinox is viewed as the beginning of spring and fall The term is also used for each of the two points on the celestial sphere at which the ecliptic and the celestial equator intersect, i e the points occupied by the Sun at equinox
