Practice with Coordinates and time:

1. For the South Pole Optical Telescope, what range of declinations could be observed and to what altitudes did these correspond?
2. Assume that the Local Sidereal Time (LST) is 0 h and the observatory is Rosemary Hill Observatory (RHO). What is the Right Ascension of the point on the sky on the horizon and due North? due East? due West? due South? What are the hour angles of those points?
3. The latitude of RHO is about 30 degrees North. What is the altitude of the zenith? of the North Celestial Pole?
4. What is the declination of the point on the horizon due south of an observer whose latitude is 48 degrees north?
5. At RHO what is the declination of a star at the zenith? due South? due East? due West? due North?
6. The images taken with the 18 inch system are about 6.5x9 arc minutes with the long axis east-west. Assuming that the object being imaged is on the celestial equator, how long will it take a star to trail the width of the image if the telescope tracking is not turned on?
7. Thunder Bay, Ontario is located at latitude: 48 degrees, 22 minutes north, longitude: 89 degrees, 19 minutes west. They keep their clocks set to Eastern time zone time. At local solar noon on December 21 what time will clocks in Thunder Bay read?
8. When the Greenwich Sidereal Time (ST0) is 11h30m, what is the LST in Thunder Bay?
9. Exactly thirty days later, what will be the LST in Thunder Bay?
10. The longitude of Gainesville is about 82d30m west. If the Sidereal Time at midnight in Greenwich is 5h30m what is the LST at that same instant in Gainesville? At midnight EST in Gainesville that same night, what will be the LST?
