Reflection for Celestial Sphere lab

I'd say I knew a lot of the basics of why we have seasons and equinoxes before this lab, but being able to see them illustrated was very useful for solidifying ideas. I'm still having issues with positioning sunrise and sunset, so I'm sure there are a few mistakes in that area, but other than that, I think I've learned what I was meant to learn. : )

  1. Sunrise and set mean the Sun has to come over the horizon (or go below). The horizon in Mt. Vernon would be with the blue plane pointing to 42 degrees on the celestial sphere... time would be determined as you divide the circle into 24 hours and where would be determined by the azimuth of the Sun as it comes above (or below) the horizon.
