The sun rises from somewhere on the easternhorizon every time it rises, regardless of
the day, the month, or the place on the earth where you're watching for it. Even in the
places where the sun only rises once a year, it rises in the east.
On March 21, the Sun is generally fairly close to being right over the equator.
March 21 is the average date of the northern hemisphere vernal equinox. However, the exact times of the solstices and equinoxes can vary a day or two either way, depending on the cycle of leap years.
In 2010, the March equinox occurred at 17:32 GMT on March 20, and the September equinox was at 3:09 GMT on September 23.
You can check the U.S. Naval Observatory's web site at "Earth's Seasons"
to see the dates and times of the solstices and equinoxes.
The declination of the Sun on March 21 varies each year but it is generally around 0 degrees. The declination of the Sun refers to its angular distance north or south of the celestial equator.
Depending where you live the sunset might be more north or south but the sunset always sets in the west
During the equinoxes - March 21, and December 23, approximately - the Sun rises directly to the East.
Where exactly? It varies, depending on the exact date in March, the lattitude, the longitude, and the time zone used.

When does the sun have adeclination of zero degrees today but will have a negative declination tomorrow?
The Sun has zero declination at the two equinoxes on March 21 and September 21 (approximately). At the autumn equinox in September it crosses the plane of the Earth's orbit from north to south, so its declination goes from positive to negative.
What seasons do equinoxes occur?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
At what angle does the sun's rays hit the earth on dec 21 sept 23 June 21 and March 21 in Buffalo NY?
In fact, the Sun's rays strike Buffalo, NY at various angles as the Sun rises on the eastern horizon, crosses to the South, and then sets in the west. The only angle that we're really interested in is the "local apparent noon", or "Sun transit" angle. Buffalo is a large city, and the angle will be different on the north edge or the south edge. Niagara Square, pretty close to the city center, is at latitude 42.88 degrees north. Consulting the Nautical Almanac Online for 2011, I see that the declination of the Sun as it passes Buffalo on March 21, 2011 will be 0 degrees 16 minutes north, or 0.27 degrees. On June 21, 23 degrees 26 minutes north, or 23.38 degrees. On September 21, the Sun will be at declination 0 degrees 39 minutes North, or 0.65, and on December 21, 23 degrees 26 minutes SOUTH, or 23.36. So, on March 21, the "local apparent noon" Sun elevation angle above the southern horizon will be 90 minus Buffalo's latitude of 42.88 degrees PLUS the declination of 0.27 degrees, or 47.39 degrees On June 21, the Sun's maximum elevation will be 90 minus 42.88 PLUS 23.38, or 70.5 degrees. I'll let you calculate the other two, remembering to subtract the declination when it is south.
What is the right ascension and declination of constellation Capricornus?
The right ascension of Capricornus is approximately 21 hours, and the declination is around -20 degrees. These coordinates indicate the position of the constellation in the celestial sphere.
How many times will the suns perpendicular rays cross earths equator between March 1 of one year and March 1 of the next?
Sed says: TWICE. From the Northern Hemisphere perspective: Once on March 20/21 .... sun's rays moving northward, and again on Sept 20/21 with sun's rays moving southward.
When does the sun have adeclination of zero degrees today but will have a negative declination tomorrow?
The Sun has zero declination at the two equinoxes on March 21 and September 21 (approximately). At the autumn equinox in September it crosses the plane of the Earth's orbit from north to south, so its declination goes from positive to negative.
During which two times of the year is the declination of the sun changing most slowly?
The declination of the sun changes most slowly near the times of the summer and winter solstices. At these points, the sun reaches its highest and lowest points in the sky, causing its declination to change gradually as it approaches these extreme positions.
At what point sun's declination is minimum?
The minimum declination of the sun occurs around the winter solstice, which is around December 21st in the Northern Hemisphere and June 21st in the Southern Hemisphere. At this point, the sun reaches its southernmost or northernmost point, resulting in the lowest declination.
What is significant about equinoxes?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
What seasons do equinoxes occur?

Does equinox mean winter?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.

Why do equinox happen?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
What latitude is the sun directly overhead at noon on may 5th August 10th abd October 15th?
Anywhere where the declination of the Sun is equal to your latitude. You can look up the declination of the Sun in the Nautical Almanac. Declination is the angle of a celestial body north or south of the celestial equator; the celestial equator is the same as the terrestrial one, extended out into space. On June 21, the Sun's declination is about 23.5 degrees north; on the equinoxes, it is zero. On December 21, the Sun's declination is about 23.5 degrees south.
How many times each year does the sun rise and set at the south pole?
As seen from the south pole, the sun rises once, around September 21, and sets once, around March 21, each year.
What is the right ascension and declination of Microscopium?
Right ascension is 21 h and declination is −36°.
