UCF Fall 2009 AST 2002 Sec 0004 Solutions to HW #3 Motion of the Sky: Note - I took points off if you didn't give an explanation for your answers, even if your answers are right. Ya gotta follow directions! Exercise #1: Sun will appear next to the same constellation form sunrise to sunset. Over the course of a day, the Sun doesn't really move much with respect to the stars, so it's as if it too is stuck on the celestial sphere. Exercise #2: EDCBA Note that in this case "day" refers to the 24-hour period from midnight to midnight. It doesn't really refer to just the 24-hour period starting at sunrise. E and D rise before sunrise, and B and A rise after sunrise. Exercise #3: BACD A lot of people found this one tricky. Recall what the "eastern part of the sky" means -- it refers to half of the dome of the sky above your head. Which half? Well the half that's on the eastern side of your meridian. The meridian runs from the due-north horizon up to your zenith and then back down to the due-south horizon.
