The planisphere rotates about the North Celestial Pole, which is approximately in the location of what star? (Give the star's name--you will have to check your SC002 chart.) 2. Which way should you rotate the planisphere to correspond with the movement of the stars with increasing time? (Hint: Clockwise or counterclockwise?) 3. What is the name for the imaginary line on the sky, shown in the planisphere window, where the planets and Moon can be found? 4. What is the name for the imaginary line that runs from the north point to the south point on the horizon? 5.

An object located halfway between the center and the edge of the star chart will be _?_ degrees above the horizon. 16. The times for using these star charts become earlier in the evening for dates later in the year. This is due to the revolution of the _?_ around the _?_. 17. What object is located on the star chart at coordinates approximately 0 degrees azimuth, and 40 degrees altitude?
