Polaris, also known as the North Star, is positioned nearly directly above the North Pole. Therefore, its altitude in degrees above the horizon corresponds closely to your latitude in the Northern Hemisphere. For example, if you are at a latitude of 40 degrees north, Polaris would be approximately 40 degrees above the horizon.
If you are at a latitude of 34 degrees north, Polaris, which is located nearly at the North Celestial Pole, will appear approximately 34 degrees above the northern horizon. This means that the altitude of Polaris in the sky corresponds closely to your latitude. Thus, if you are standing at 34 degrees north latitude, Polaris will be directly overhead at that angle.
Polaris, also known as the North Star, is located nearly directly above the North Pole. In Oswego, New York, which is situated at a latitude of approximately 43.4 degrees North, Polaris will be found roughly 43.4 degrees above the northern horizon. This angle corresponds closely to the observer's latitude, making Polaris a useful reference point for navigation.
Seattle's latitude is about 47.6 degrees North. So the altitude of Polaris above the northern horizon is always within about 1/3 degree of that angle as seen from there.
The altitude doesn't depend much on whether the night is clear.If you live in the northern hemisphere, the altitude of Polaris above the horizon will APPROXIMATELY be equal to your latitude. If you live in the southern hemisphere, Polaris will be BELOW the horizon, as many degrees as you are south of the equator.
In the northern hemisphere, we used to rely on locating where Polaris is in the sky, which is almost directly over the North Pole. The angle of Polaris above the horizon corresponds to your latitude so Polaris helped many sea navigators to find their was north or south.
37 degrees north latitude

You would never see Polaris there because it would always be 41 degrees or more below the northern horizon. On the other hand you can see many fine stars and constellations that are never seen in North Europe or the north of the USA and Canada.

From any location north of the Equator: The north star (Polaris) is in the sky, always due north of you, and always as many degrees above the horizon as your latitude north of the equator. It makes no difference what time you look for it, or where you are in an east or west direction.
The altitude of the highest point of the rainbow that you see is (42 degrees) minus (the altitude of the sun above the horizon behind you). If the sun is sitting right on the horizon ... just risen or just about to set ... then the highest point of the rainbow is about 42 degrees above the horizon opposite the sun. If the sun is higher, then the rainbow is lower, by the same amount. If the sun is more than about 42 degrees above the horizon, then any rainbow you might otherwise see is entirely below the opposite horizon, and you don't see one.
Depends on the height of the aircraft above ground.
