## How do you calculate latitude and declination?

The declination of Sirius is -17° (from the text) and its zenith distance is (90° – the altitude) = 90° – 51° = 39°. Since it is South of the Zenith we add the zenith distance to the declination to find our latitude: **our latitude = the declination + the zenith distance = -17° + 39° = +22°** (North latitude).

## What do you mean by latitudes and longitudes?

Latitude and longitude are **angles that uniquely define points on a sphere**. … Latitudes of +90 and -90 degrees correspond to the north and south geographic poles on the earth respectively. Longitude is defined in terms of meridians which are half-circles running from pole to pole.

## What is declination diagram?

## Where is my Zenith?

Zenith in astronomy terms is **the point in the sky directly overhead**.

## Is the equator latitude or longitude?

The Equator is the line of **0 degrees latitude**. Each parallel measures one degree north or south of the Equator with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N and the latitude of the South Pole is 90 degrees S.

## At which location will the altitude of the star Polaris be 0o?

Notice that that for a spot at latitude θ the view of the sky makes the same angle θ with **the north pole**. Since Polaris is at an extension of the north pole this is the angle at which Polaris lies above the horizon. Therefore for Polaris to be 43o above the horizon we must be standing at a latitude of 43o .

## What is the latitude of the North Pole?

90.0000° N 135.0000° W

## What is north latitude and south latitude?

Latitude. Lines of latitude measure north-south position between the poles. The **equator is defined as 0 degrees the North Pole is 90 degrees north and the South Pole is 90 degrees south**. Lines of latitude are all parallel to each other thus they are often referred to as parallels.

## How do you find GHA?

So to calculate the GHA of a star all you have to do is: **GHA(star) = SHA(star) + GHA(aries)**.

## What is our latitude?

Latitude is your distance North or South from Earth’s equator measured in degrees. **0° is the latitude at the equator** +90° is the latitude at the North Pole and -90° is the latitude at the South Pole.

…

## What is the latitude and longitude of Syracuse NY?

43.0481° N 76.1474° W

## How do you find the altitude of Polaris?

Align the 0° edge of the compass with the horizon. Keeping the 0° edge flat against the horizon **lift one arm of the compass until it points directly at Polaris**. Read off the angle. This is the altitude of Polaris from your location on Earth.

## What’s the altitude of Polaris?

0 degreesRemember that the altitude of Polaris is **0 degrees if you are observing from the equator** (0 degrees latitude) and 90 degrees if you are observing from the north pole (latitude 90 degrees) and it is also true for intermediate latitudes.

## Reading Sun Path Diagrams

## How do you calculate observer latitude?

The observer’s latitude is easily calculated by **forming the algebraic sum or difference of the declination and observed zenith distance z (90°-Ho) of the sun** depending on whether the sun is north or south of the observer (Fig. 6-2). Northern declination is positive southern negative.

## How do you find declination?

The following equation can be used to calculate the declination angle: δ=−23.45°×cos(360/365×(d+10)) where the d is the number of days since the start of the year The declination angle equals zero at the equinoxes (March 22 and September 22) positive during the summer in northern hemisphere and negative during winter …

## What is the altitude of the observer?

Altitude (alt.) sometimes referred to as elevation (el.) is **the angle between the object and the observer’s local horizon**. For visible objects it is an angle between 0° and 90°. Azimuth (az.) is the angle of the object around the horizon usually measured from true north and increasing eastward.

## How do you find the LHA of the sun?

LHA is everything **in the full circle** except for the small angle from the GHA of the sun to our meridian of longitude. That small angle is easily determined (150° minus 40° = 110°). Now that result is subtracted from 360° to give LHA: 360° minus 110° = 250°. So in this case the LHA of the sun is 250°.

## Is latitude and declination the same?

Declination (DEC) is **the celestial sphere’s equivalent of latitude** and it is expressed in degrees as is latitude. For DEC + and – refer to north and south respectively. The celestial equator is 0° DEC and the poles are +90° and -90°. Right ascension (RA) is the celestial equivalent of longitude.

## What is the latitude for an observer at the equator?

90◦Answer: The altitude of the celestial equator is **90◦−** the observer’s latitude. At the poles the latitude is 90◦ N or 90◦ S. So 90◦−90◦ = 0◦. See also what does red algae eat

## Which reference line passes through both the geographic North Pole and the geographic South Pole?

The Equator**The Equator** is an imaginary reference line drawn around the Earth halfway between the North and South poles. The Earth rotates daily on its axis and the North and South poles are the two points where the axis enters and exits the Earth. See also what type of government best describes sparta?

## How do you find the latitude using the North Star?

**Use the sight line on the top of the aiming beam** to align the beam with the North Star. Use the protractor to measure the angle between the beam and the horizon (which is 90° to the plumb line). This angle is your latitude.

## How do you use latitude on Polaris calculator?

## Which line is longitude?

the prime meridianLongitude is the **measurement east or west of the prime meridian**. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude.

## What is latitude Brainly?

In geography latitude is **a geographic coordinate that specifies the north–south position of a point on the Earth’s surface**. Latitude is an angle which ranges from 0° at the Equator to 90° at the poles. Lines of constant latitude or parallels run east–west as circles parallel to the equato.

## What is the latitude of an observer if they find the altitude of Polaris is 40 above the horizon?

Which graph best represents the relationship between the latitude of an observer and the observed altitude of Polaris above the northern horizon? A) due east B) due south C) due west D) due **north 60**. An observer on a moving ship notices that the altitude of Polaris increases each night.

## What is latitude angle?

Latitude is an angle (defined below) which **ranges from 0° at the Equator to 90° (North or South) at the poles**. Lines of constant latitude or parallels run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.

## What represent 90 in celestial sphere?

Points on the horizon are called directions. The horizon circle is divided into 360°s with 90°s between each of the four cardinal directions of North South East and West. **The Zenith** is the point on the Celestial Sphere directly above the observer.

## How do you solve LHA?

**LHA = GHA – Longitude (if Long is West)** e.g. In this example our Longitude is 10° E. The GHA of the sun is 60°. The diagram shows that the angle between us and the sun must be the GHA + our Longitude.

## What latitude does the North Star appear closest to the horizon?

(30 degrees latitude)– Polaris is located 30 degrees above the northern horizon. This trend continues until the traveler reaches the geographic (not magnetic) North Pole. At this point (**90 degrees latitude**) Polaris is 90 degrees above the northern horizon and appears directly overhead.
