Astronomy 108 Section 1 Lab #2 Michael Curran At 7:10pm on Wednesday January 30 th I started making my astrological observations for this lab. Polaris was quite easy to find, hanging over a group of small bushes and assorted trees that were directly in my line of sight. Using my star map and the instructions provided I searched the northwestern sky for Cassiopeia, which I found tilted into an “M” position high in the sky, also hanging over the assorted small bushes.

The Big Dipper also seemed to have moved from it’s initial location, now appearing higher in the sky (with the handle almost in line with both Polaris and Cassiopeia) and with the two pointer stars of the bowl now pointing towards Cassiopeia in addition to Polaris. It had come to rest hanging over a house to my east. Based upon these observations conducted four hours apart, I can conclude that the constellations in the night sky appear to be moving in an east to west direction fixed about the North Celestial Pole (and thusly, fixed about Polaris)....
