Subtract your latitude from 90° and that will give the the decollation of circumpolar stars.
In northern New Zealand, my latitude is 35°. If I subtract that from 90°, I get 55°. So stars with Declination great than 55° are circumpolar for me.
The angle of the Sun in the sky, its maximum height above the horizon, depends on a measurement called its declination, which varies over a range of ±23.5 degrees. The Sun's declination is zero at the equinoxes, and is +23.5 degrees at the summer solstice (in the northern hemisphere), the longest day, and -23.5 degrees at the winter solstice, the shortest day. Declination is the Sun's latitude on the celestial sphere, and the declination of any obect is equal to the latitude of a set of points along a line of latitude on the Earth's surface at which it passes overhead.
That depends on the date, since the sun itself moves through the entire range of RA during the year. It also depends on the star's declination. Viewed from the northern hemisphere, for example, the greater a star's declination, the earlier it rises, and if its declination is greater than the complement of the observer's latitude, then it never sets.
The Sun appears larger than other stars because it is much closer to Earth compared to other stars. This proximity makes the Sun appear larger and brighter in our sky. In reality, the Sun is an average-sized star compared to the vast range of sizes of other stars in the universe.
Massive stars can appear in a range of colors depending on their surface temperature. They can range from blue (hottest) to white, yellow, orange, and red (coolest). The color of a massive star can provide clues about its temperature and stage of life.
Mars has a temperature range that can vary from -13 Celsius to 37 Celsius, depending on the location and time of day. This range makes it a planet with significant temperature fluctuations due to its thin atmosphere and distance from the Sun.
To calculate the range of declinations for which stars are circumpolar, you need to know the observer's latitude. Circumpolar stars are those that never set below the horizon. For a given latitude ( \phi ), the declination (( \delta )) of circumpolar stars ranges from ( +90^\circ - \phi ) to ( -90^\circ + \phi ). Thus, if you are at a latitude of, say, 40°N, circumpolar stars would have declinations between ( +50^\circ ) and ( -50^\circ ).
Declination can range from +90 degrees (north) to -90 degrees (south).
-90° to +90°
The range of values for celestial declination is from -90 degrees to +90 degrees. A declination of 0 degrees corresponds to the celestial equator, while +90 degrees denotes the north celestial pole and -90 degrees denotes the south celestial pole. This range allows for the precise positioning of celestial objects in the sky relative to Earth's equatorial plane.
The range of the Snowy Owl Nyctea scandiaca is circumpolar - arctic regions of new and old world.
Declination, which measures the angle between the direction of a celestial object and the celestial equator, ranges from +90 degrees to -90 degrees. A declination of +90 degrees indicates the North Celestial Pole, while -90 degrees indicates the South Celestial Pole. Values between these extremes represent the position of celestial objects in the sky relative to the celestial equator.
No it can not.
The angle of the Sun in the sky, its maximum height above the horizon, depends on a measurement called its declination, which varies over a range of ±23.5 degrees. The Sun's declination is zero at the equinoxes, and is +23.5 degrees at the summer solstice (in the northern hemisphere), the longest day, and -23.5 degrees at the winter solstice, the shortest day.

It depends on where in the Rockies you are. New Mexico? Colorado? Wyoming? Montana and Idaho? There will also be the standard deviations from the norm based on altitude, solar activity, weather, local anomalies, etc. The deviation will range from about 9o in northern New Mexico (which is the southern end of the range) to about 15o in northern Montana and the Idaho panhandle. Use the link to the NOAA web page where you can get a magnetic declination for any geographic location within the U.S. along with some correction factors. It is even searchable by zip code to make it really easy to approximate things quickly.
No frequencies in that range appear on the list you provided with the question.
