The altitude of polaris for an observer is always the same as your latitude so it would be 64oN
On the horizon
You would face north.
If the altitude of Polaris is 43 degrees above the northern horizon, then the observer is located somewhere within roughly 1/2 degree of 43 degrees north latitude.

At the Equator.
If an observer in Pennsylvania measures the altitude of Polaris to be 40 degrees, they could be approximately 40 degrees north of the equator, which would imply a latitude close to 40 degrees north. This is because the altitude of Polaris above the horizon is equal to the observer's latitude in the Northern Hemisphere.
The altitude of Polaris and the latitude of an observer are directly related. The altitude of Polaris in the sky is approximately equal to the observer's latitude in the Northern Hemisphere. The higher the latitude, the higher Polaris will appear in the sky.
The earth's axis of rotation is tilted relative to its orbit around the sun, causing Polaris to align with the earth's axis. When an observer measures the altitude of Polaris above the horizon, they can determine their latitude because Polaris' altitude corresponds to the observer's angular distance from the North Pole.
Polaris does not appear to move.
