Image of the Sun (pt. 2)


This was my second of three times looking at the image of the Sun as it appears on a folder through the quadrant. Here's a quick look at the differences between my two observations:

                       Part 1                                       Part 2
                    October 2                               November 8
                  4:20 pm EDT                             3:45 pm EST
                  23° altitude                               9° altitude

The shape on both days was approximately the same, but again, not spherical like you would imagine the Sun's reflection being. The change in altitude would also need to take into account the fact that we changed from Daylight Savings to Standard Time, meaning that when I looked that the Sun's image for the second time, it was equivalent to 4:45 when I had done part 1, so the Sun would have been lower in the sky anyways; but there is also the factor that the Sun is getting lower in the sky as we move toward winter. So there are two factors that made the altitudes so different from one another.
