Does the declination of the North Celestial Pole change with location?

No. The declinations of the various stars are fixed, and don't vary over time. The declinations of objects within our solar system, such as the Sun, Moon and the planets, will vary as each of those objects move along in their own orbits around the Sun.
And saying that "the declinations of stars don't change" isn't precisely correct, but they do not change within human lifetimes. Over the course of hundreds of years, these will vary slightly.

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.
Over time the wobble in earths rotation will change what effect will this have?
The effect this has is that the location in the sky of the North Celestial Pole is constantly moving. The amount of change over the course of a human lifetime is not perceptible to people who don't make calibrated astronomical measurements.
How many degrees is polaris from true north?
There is no standard degree that is always between true north and magnetic north. Depending on where your location is will their be a declination. Because true north is a location and magnetic north is a field that is at a constant slow move.
Where in the sky above boulder is the north celestial pole?
We don't want to shock you, but you need to understand that there are "Boulders" in Colorado, Idaho, Montana, Utah, Virginia, West Virginia, and Wyoming. We don't know which Boulder you're writing from, so the best answer we can give is the generic one, that applies to any and all Boulders: -- The north celestial pole is the point in the sky located exactly north of your location, and an angle above the northern horizon equal to your north latitude. -- The point is marked approximately, but not precisely, by the moderately bright star 'Polaris', also referred to as the 'North Star'. Note that the north celestial pole is visible from everywhere in the Northern Hemisphere, and from nowhere in the Southern Hemisphere.
How much higher is the sun at noon compared to midnight at latitude 80 degrees north - on days where the sun never sets?
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
On the celestial sphere what is the North Stars declination?
The declination of Polaris (the north star) is: + 89° 19' 39'That's just 0.6725 degree from the north celestial pole.
Does a star that is located 30 degrees north of the celestial equator have 30 degrees declination?
Yes. "Declination" on the celestial coordinate system is the counterpart of "latitude" on the terrestrial coordinate system. Positive and negative declination correspond respectively to north and south latitude.
A star that is located 30 north of the celestial equator has?
'Declination' of +30
When does the Sun have declination 0 degree today but will have a negative declination tomorrow?
Declination is the angular measurement of a celestial body north or south of the "celestial equator". You can think of it as the equivalent of "celestial latitude". The "fixed stars" don't have any change in declination. (Well, they _DO_, but only very slightly and VERY slowly.) The Sun, Moon, and planets all have their own paths within the solar system, so their declinations will change on a day-to-day basis. The Sun is at a declination of zero precisely at the time of the equinox. In September, the Sun's declination is decreasing, and it goes negative immediately after the moment of the equinox. This is generally on September 21, but this can vary a day either way depending on the cycle of leap years.
Is The south celestial pole is located at a declination of -90 degrees?
The Celestial Poles are the infinite extension of the North and South Poles from the Earth into space. The North Star or Polaris, is within 1 degree of the North Celestial Pole. There is no equivalent star for the South Celestial Pole.
How do you find celestial points?
You measure the angles from east from the first point of Aries (which is the place in the sky where the Sun crosses the celestial equator at the March equinox) and north from the ecliptic (declination).
What is the distance measured in degrees north and south of the equator is referred to as?
Declination (positive and negative respectively) is the angular distance between north and south of the Celestial Equator.
What is the magnetic declination in Jasper al?
The magnetic declination in Jasper, Alberta, Canada is approximately 18 degrees east. This means that magnetic north is 18 degrees east of true north in this location.
What is a stars location determined by?
Astronomers use the coordinate system of RA right ascension also called hour angle, and Declination (Dec)RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from a zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. RA is always zero on the meridian of the celestial sphere which passes through the celestial poles and first point of Aries. Declination is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of thecelestial equator. Therefore, points north of the celestial equator have positive declinations, while those to the south have negative declinations. * An object on the celestial equator has a dec of 0°. * An object at the celestial north pole has a dec of +90°. * An object at the celestial south pole has a dec of −90°.
What is an agonic point?
An agonic point is o location where a magnetic needle points North without declination.
What is a magnet declination?
Magnet declination is the angle between magnetic north and true north. Declination is considered positive east of truth north and negative when west.
