What is the relationship between the time of year and the angle of the sun in the sky?
The angle of the Sun in the sky, its maximum height above the horizon, depends on a measurement called its declination, which varies over a range of ±23.5 degrees. The Sun's declination is zero at the equinoxes, and is +23.5 degrees at the summer solstice (in the northern hemisphere), the longest day, and -23.5 degrees at the winter solstice, the shortest day. Declination is the Sun's latitude on the celestial sphere, and the declination of any obect is equal to the latitude of a set of points along a line of latitude on the Earth's surface at which it passes overhead.
What is of the Angle of magnetic north?
That all depends on WHERE on the earth you are located. The angle between the direction to the north geographic pole and the north magnetic pole is different at different places. Go to "Google.com" and search for "magnetic declination". You'll get plenty to read, and ways to determine what the angle is at your location.
What happens to the angle of declination as you get closer to poles?
when you are close to the magnetic north pole, the declination will be so variable and unpredicatable that a magnetic compass becomes all but useless. You also need to consider the effect of local magnetic anomalies and polar wandering. felicity knows whats up<3

One hour of right ascension is equivalent to how many degrees of sky rotation?
Depends on the declination in question. There are 24 hours of right ascension in 360 degrees, so at the celestial equator (declination = 0 degrees) 1 hour of right ascension is equal to 15 degrees. But as you increase or decrease declination the right ascension lines converge to the celestial pole (like longitude lines on a globe). The angle covered by 1 hour of right ascension is therefore equal to (15 degrees x cos(declination) ), so at the celestial poles (declination = +/- 90 degrees) 1 hour of RA is 0 degrees.
What is the angle of correction called?
Magnetic 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.
How is the altitude angle and zenith angle related to latitude and declination?
solar altitude angle= (90 degree - zenith angle )
In order to find true north with a compass you must use an angle of correction called?
angle of magnetic declination
What is the optimun angle of declination?
Zero degrees! If the angle of declination is 0°, then magnetic north is exactly the same as true north, making it much easier to navigate. But really, there isn't any "optimum" angle. One angle is just as good as another as long as you know how to correct for it in the right way.
How do you find magnetic direction?
The angle between the direction your compass points and the direction you're facing is the 'magnetic azimuth'. The angle between the direction to the north pole and the direction you're facing is the 'true azimuth'. They are virtually never the same angle. The difference between them is the 'magnetic declination' or the 'compass declination' in the place where you are at in which.
To convert a grid azimuth to a magnetic azimuth you will need to know g-m angle. where would you look for this piece of information?

Blank is how far around the map the star is?
Declination, which is measured as an angle, north is positive and south is negative. The declination of a star etc. is also the latitude at which the star passes overhead.
The angle of difference between the geographic and magnetic poles is called the declination How does the declination change as you move north from where you live?
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.
What is inclination and declination?
Inclination is measured as the angle at which the satellite crosses the equator while passing from the southern hemisphere to the northern hemisphere. Declination is the difference between magnetic North as reported by a compass and true North.
What is the angle between the geographic North Pole and the direction in which a compass needle points is called magnetic?
Magnetic declination
What tool is used to measure a angle?
A protractor is used to measure angles.When surveying a theodolite is used.There are a number of tools on the market that perform angle measurement.
