What latitude on earth is a celestial pole 45 above 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.
What is the altitude of polaris above the horizon at the tropic of cancer?
Polaris will be 23.5 degrees above the northern horizon when viewed from the Tropic of Cancer.
What is the Altitude of the sun above the northern horizon at noon at 4 degrees South latitude on the summer solstice?
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.
Can the north start be used to calculate latitude?
I think you mean the 'North Star' ; note the spelling ; NOT 'Start'. It also goes by the name of 'Pole Star' and 'Polaris'. When directly above (90 degrees) you are at the North Pole. When its angle of elevation above the horizon is 89 degrees. you are at latitude of 89 degrees. When you are at latitude 49 degrees (49th parallel), it is 49 degrees above the horizon. When you are at the Equator ( latitude 0 degrees) it is on the horizon. However, you probably cannot see it at this latitude because dust dirt particles in the air. South of the Equator you cannot see it , as it is below the horizon. In the Southern Hemisphere there is no corresponding pole star. Navigators use the constellation named the 'Southern Cross', in order to determine latitude.
What is the angle between the zenith and North celestial pole if you are at 37 degrees latitude?
If your latitude is 39 degrees north, then the north celestial poleis 39 degrees above your northern horizon.If your latitude is 39 degrees south, then the north celestial poleis 39 degrees below your northern horizon.
What latitude on earth is a celestial pole 45 above 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.
Is 55 degrees above the horizon very low in the sky - ie very close to the horizon?
If the horizon is on a level line of sight, a vertical line directly above the observer forms an angle of 90 degrees. 55 degrees would be quite high, being above 45 degrees.
Is the sun considered to be low in the sky when it is 56 degrees above the horizon?
No, 56 degrees above the horizon isn't "low". "Low in the sky" is less than 20 degrees elevation or so.

Does the sunset on Christmas day in the Antarctic?
No, the sun stays above the horizon for the whole of Christmas day, at an angle of 23.5 degrees above the horizon.
What is the nothernmost latitude in the US from which the entire southern cross is visible in degrees N?
The southernmost prominent star in Crux is Alpha Crucis, which is at declination -63 degrees 5 minutes (or thereabouts). The northernmost latitude at which Alpha Crucis can be seen is therefore slightly south of 27 degrees north. The area assigned to Crux extends further south than that, but I presume you're interested mainly in the asterism (the "Cross"). At 27N, Acrux will fall just short of clearing the horizon at midnight (by about a fifth the diameter of the full moon); you'd need to be at about 26 degrees 50 minutes or so to ever see it rise above the horizon. The only states from which it's ever possible to see the entire Southern Cross are therefore Hawaii, southern Florida, and the southernmost tip of Texas.
What is the angle between the zenith and North celestial pole if you are at 37 degrees latitude?
If your latitude is 39 degrees north, then the north celestial poleis 39 degrees above your northern horizon.If your latitude is 39 degrees south, then the north celestial poleis 39 degrees below your northern horizon.
The number of degrees of arc that Polaris is above the horizon depends on what?
Your latitude!
What is the altitude of polaris above the northern horizon for observer a?
90 degrees
What is the altitude of Polaris above the horizon at the tropic of Capricorn?
it's 23 degrees below the horizon; you won't see it.
