Now go outside and use the information you gathered in parts A–C to locate Ursa Minor and Polaris in the night sky. Measure the azimuth and altitude of Polaris using the following image and directions as a reference. For altitude, remember that the horizon is 0° and the zenith, directly overhead, is 90°. Report the azimuth and altitude of Polaris at your location in the answer space. Measuring the azimuth: Use your compass to identify the direction you are facing as you view Polaris. The direction of Polaris corresponds to the degrees of azimuth shown here. The direction of Polaris corresponds to degrees of azimuth in the compass. Measuring the altitude: Hold your hand at arm’s length and close one eye. Use the hand measurements below to measure the height, or altitude, of Polaris above the horizon. Note that not everyone’s hands are the same size, so as a reference for measurement, Ursa Major (the Big Dipper) is approximately 25° across. An image shows the measurement of altitude by hand at arm's length.
