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.
Looking toward the north, the ray from you through the point 70 degrees above the horizon. 90 degrees would be directly overhead.Notation such as this is used to announce sightings of the International Space Station, for example:
The North star will be 75 degrees above the horizon. Whatever degree you are at latitude, the North star will be the same degrees up. So at the north pole (90 degrees north), the star will be at the zenith (straight up). While at the equator (0 degrees north) the star will be at the horizon.
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
The angle of Polaris above the northern horizon is very nearly equal to your north latitude, within about 1/3 of a degree. So it's over your head when you stand at the north pole, it sits nominally on your north horizon when you stand anywhere on the equator, and if you're south of the equator, you can never see it at all.
At the Tropic of Capricorn (approximately 23.5 degrees south latitude), Polaris, the North Star, is not visible and is located below the horizon. Polaris can only be seen in the Northern Hemisphere and its altitude above the horizon increases the further north you go.

The altitude of the celestial north pole above the northern horizon is exactlythe observer's north latitude on the earth. The center of Frankfurt is very closeto 50° North latitude.
The angle of Polaris above the northern horizon is very nearly equal to your north latitude, within about 1/3 of a degree. So it's over your head when you stand at the north pole, it sits nominally on your north horizon when you stand anywhere on the equator, and if you're south of the equator, you can never see it at all.
60 degrees north long
At 40 degrees latitude, Polaris, also known as the North Star, will appear approximately 40 degrees above the northern horizon. This is because the angle of Polaris above the horizon corresponds closely to the observer's latitude in the Northern Hemisphere. Therefore, if you are at 40 degrees north latitude, Polaris will be positioned directly overhead at the North Pole and will gradually lower to the horizon as you move south, reaching 0 degrees at the equator.
If the star Polaris is 29 degrees above the horizon, then your latitude is about 29 degrees North.Polaris is not exactly above the North Pole, but it is only about one-half degree away from that.
On the winter solstice at a latitude of 57 degrees north, the sun will be about 33 degrees below the horizon at night. This is because the tilt of the Earth causes the sun to not rise above a certain angle during the winter months at this latitude.
In that case, you live at a latitude of 35 degrees north.
At the Tropic of Capricorn (approximately 23.5 degrees south latitude), Polaris, the North Star, is not visible and is located below the horizon. Polaris can only be seen in the Northern Hemisphere and its altitude above the horizon increases the further north you go.
Fairbanks is located at latitude 64.8 degrees north, so the north celestial pole is always 64.8 degrees above the horizon. Polaris itself is presently about 0.7 degrees from the celestial pole, so its altitude above the horizon will vary between 64.1 and 65.5 degrees during the course of a sidereal day.
