To answer the question with any real accuracy, you would also need to know the precise TIME, in GMT, of local apparent noon, because on November 17 each year, the Sun is apparently moving to the south at 0.6 minutes per hour. You will need a copy of the Nautical Alamanac, in order to look up the declination of the Sun at each hour. The link to the online Nautical Almanac is below.
If you observe the Sun at an elevation of 44 degrees at local apparent noon, then your latitude is 90 minus your sextant reading minus your south declination or plus your north declination. At noon GMT on November 17, 2011, the Sun is at 18 degrees, 57.7 minutes south declination. I'll round it off to 19 degrees, since neither the time nor the elevation in this question is all that precise anyway.
So, 90 - 44 is 46 degrees, minus 19 equals your latitude of 27 degrees north.
The celestial pole that is 45 degrees above the horizon is located at a latitude of 45 degrees. This means that an observer at this location would see the celestial pole positioned halfway between the horizon and the zenith.
The angle between the zenith and North celestial pole at a latitude of 37 degrees is equal to 53 degrees. This is because the North celestial pole is located at an altitude above the horizon that is equal to your latitude. Subtracting this from 90 degrees (the angle between the zenith and the horizon) gives you 90 - 37 = 53 degrees.
The observer must be 15.5 degrees south of the Arctic circle, so 51.1 degrees north approximately.
Yes, the North Star (Polaris) can be used to calculate latitude in the northern hemisphere. By measuring the angle between the horizon and the North Star, you can determine your latitude. The angle is equal to your latitude.
The angle of Polaris above the horizon is equal to the latitude of the observer. This means that at the North Pole (90 degrees latitude), Polaris would be directly overhead (90 degrees above the horizon), and at the Equator (0 degrees latitude), Polaris would be on the horizon (0 degrees above the horizon).

At 5 degrees latitude, either north or south, the sun sets on every night of the year. So it seems to me that at midnight, it must be below the horizon in EVERY direction.
The angle of Polaris above the horizon is equal to the latitude of the observer. This means that at the North Pole (90 degrees latitude), Polaris would be directly overhead (90 degrees above the horizon), and at the Equator (0 degrees latitude), Polaris would be on the horizon (0 degrees above the horizon).
At the summer solstice, the Sun is 23.5 degrees north of the celestial equator. Love Field, Dallas, TX is at 32.8 degrees north.A "noon fix" is achieved by observing the altitude of the Sun at "local apparent noon", when the Sun is at its highest point in the sky. You can calculate your latitude by taking 90 degrees minus the observed angle above the horizon, or "altitude", and subtracting the declination, or Sun's angle north (or south) of the equator.In this case, we need to work the problem backwards. So take 90 - (latitude) + declination, or 90 - 32.8 + 23.5 = 80.7 degrees.Oh, one other thing; this is the altitude of the Sun above the SOUTHERN horizon. The Sun will never appear north of Dallas at noon. The question asks about the northern horizon. We could calculate the angle above the northern horizon as 180-80.7 or 99.3 degrees above the northern horizon.
Your latitude!
30 degrees for observers at a latitude of 30 degrees north
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.
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.
The angle between the northern horizon and the North star Polaris at a latitude of 75 degrees north is 15 degrees. Polaris is positioned 90 degrees above the northern horizon at the North Pole (90 - 75 = 15 degrees).
