To demonstrate what I mean by shifting of the position of the sun on the horizon that I described in the previous post, here are two sunrise pictures from separate times of year at Palo Verde.  On the left is a photo I took in January and on the right is a photo I took this morning.  I know it’s not a new discovery to science, but I thought it was still cool to see, particularly because my previous experience steered me wrong in predicting the sun’s location; I had neglected to factor in the change in the earth’s tilt relative to the sun from January to May, which results in a sunrise that is further to the north.  Science is cool.
