When living in Alton NH my house had a good view of the sunsets in winter. Noticed a shadow edge of a window that was projected onto another wall. The positions of the shadow as the December days went on was evident. being due to the Earth鈥檚 orbital movement.
I painted a yard stick like strip of wood painted white and attached it to that wall. Each sunset I鈥檇 make a mark on the stick and as the days went on many marks showed the movement of the sun. As the shadow hit the 12/21 time, a couple of days later you could see the suns movement returning in it鈥檚 movement to spring. Did this many years and the movement was duplicated of course. Getting closer to spring the daily movement was great.
This back and forth movement of the sun during the year and seeing it on the stick reminded me of Simple Harmonic Motivation of the Earth while in rotation, like a pendulum. At the Autumn and spring dates, the sun鈥檚 movement is the greatest. At the peak Summer and Winter times the movement is the slowest relative to what we observe.
Conserving the sun鈥檚 movement via the window shadow gives enlightenment and helps prevent the northern latitudes 鈥淐abin Fever鈥, spring is coming! If you have the same opportunity, try it. I鈥檓 in southern Alabama winters now and maintain eastern time on a clock. At 4:15 pm (dark in the northern states), it鈥檚 still daylight here, and hour difference CDT.
I like the later sun periods, but the sun doesn鈥檛 rise as early. The Pensacola FL is latitude 30 deg 30 mins. VT/NH/ME is about 44 deg latitude, a 13.5 deg diff. The Polaris (North) star is that much closer to the horizon, and the sun鈥檚 position as well.
