At which location will Polaris be observed at the highest altitude?

At which location will Polaris be observed at the highest altitude?

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 .

Which altitude of Polaris could be observed in New York State?

On April 21, the altitude of Polaris, as viewed from a location in New York State, was measured as 41.3°.

At which location is the altitude of Polaris approximately 42?

15. At which location is the altitude of Polaris approximately 42 degrees? Elmira, cause the altitude of Polaris is 42 and alt of Polaris equals latitude of observer, and only Elmira is near the 42 degree latitude line.

At what altitude can you see Polaris?

Remember 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.

Can you see Polaris from New York?

Exactly where you see Polaris in your northern sky depends on your latitude. From New York it stands 41 degrees above the northern horizon, which also corresponds to the latitude of New York. At the equator, Polaris would appear to sit right on the horizon.

What happens to the altitude of Polaris if an observer travels due north?

As you travel northward, Polaris climbs higher in the sky. If you go as far north as the North Pole, you’ll see Polaris directly overhead. As you travel south, Polaris drops closer to the northern horizon. If you get as far as the equator, Polaris sinks to the horizon.

What is the highest altitude of Polaris?

90°
This device allowed him to measure the “altitude” of Polaris or the North Star. Polaris is directly overhead at the North Pole (90° of latitude); in other words, the angle between Polaris and the horizon at the North Pole is 90°. This angle is called “the altitude” of Polaris.

Which two locations have the greatest stream velocities?

Stream Flow and Sediment Transport Stream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second). Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.

How many degrees does the sun appear to move across the sky in 4 hours?

The sun does move across the sky at 15° per hour along its path across the sky, but when you project the positions straight down to the horizon, you will see that the bearing change with time can be much faster, depending on the height of the sun, which in turn depends on your lat and the time of year.

Is Polaris always visible?

The reason Polaris is so important is because the axis of Earth is pointed almost directly at it. So at any hour of the night, at any time of the year in the Northern Hemisphere, you can readily find Polaris and it is always found in a due northerly direction.

Where in the world will Polaris have an altitude of 90 degrees?

North Pole
(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.

Which is New York State location would Polaris be?

Therefore, for Polaris to be 43o above the horizon, we must be standing at a latitude of 43o. Perhaps Syracuse, Batavia, or Ballston Spa.

What is the latitude of Polaris above the horizon?

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 #43^o# above the horizon, we must be standing at a latitude of #43^o#.

Why is the North Star called the Polaris?

Polaris is the name of the north star in the constellation Ursa Minor. Astronomers call it the north star because as the Earth rotates on its axis, Polaris does not appear to move in the sky.

Is the north pole at the same angle as Polaris?

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.
