Problem 1 (30pts): Look a UFO! 1. One of your friend working at the tracking station in Goldstone, CA (located at a longitude, latitude and altitude of- 116 . 89 deg, 35 . 35 deg and 925 m, respectively), observes an unidentified flying object in the local sky and measures its position in the local reference every hour. The Earth is assumed to be spherical of radius 6 , 378 km and to rotate uniformly with respect to the axis passing through the poles (latitude 90 deg rotation period of 24 hours). The range (measured distance), right ascension (longitude), , and declination (latitude), , of the observed object relative to the tracking station are given on the course webpage. 2. Plot the actual observations orbit both in apparent right ascension and declination and as projected in the local horizontal plane (Please use a computer and printer)...
