Answer to Question #111256 in Astronomy | Astrophysics for Priya jaiswal

Question

Show the horizon coordinates of a star X on a celestial sphere for a location at latitude 60°N . would these coordinates be same at the latitude 30° N.

Answer 1

Let us see how the altitude of the star looks like.

The altitude is defined by the latitude because it is the angle between the direction to the star and the horizon. Latitude 60 degrees is shown as blue, latitude of 30 degrees is red.

However, the azimuths of the star for the two latitudes will be the same as the azimuth is defined by the longitude of the observer.
