* Prime Meridian: This is an imaginary line that runs from the North Pole to the South Pole, passing through Greenwich, England. It defines 0° longitude.
* Polaris Altitude: This is the angle between the horizon and the North Star (Polaris). The altitude of Polaris is equal to your latitude.
Here's how to find a location using this information:
1. Latitude: An altitude of 50° for Polaris means you are at a latitude of 50° North.
2. Longitude: Since you are crossing the prime meridian, your longitude is 0°.
Therefore, your location would be 50° North, 0° East (which is the same as 0° West). This location is in the Atlantic Ocean, near the coast of Western Europe.
