a) Draw in the location of the North Celestial Pole. Note that since this location is  directly above the Earth's North Pole it will not move in the sky as Earth rotates.  

b) Draw in star A at the specified coordinates and assume that this is time t = 0 hrs.  What will be the coordinates of star A at t = 6 hours? ________-____________________________________  _____________At t = 12 hours? _____________________________________________________ At t = 24 hours? _____________________________________________________ 

 

C) Draw in B at the specified coordinates and assume that this is time t = 0 hrs.  What will be the location of star B at t = 3 hours? 

NAAP – The Rotating Sky 3/11 

At t = 6 hours? _____________________________________________________ At t = 12 hours? _____________________________________________________ Draw in each of these locations and connect the path between the stars. For what  fraction of the day is star B visible? _____________________________ 

d) Draw in C at the specified coordinates (as best you can) and assume that this is  time t = 0 hrs. Estimate the coordinates of the star at t = 6 hours? _____________ At t = 12 hours? _____________________________________________________ At t = 24 hours? _____________________________________________________ For what fraction of the day is star C visible? ______________________________
