Mr. Scheele
As cloudy and cold as it has been here in Western Michigan, I instead used data from the US Naval Observatory for my local area as the time for the sunrise, sunset, and length of day.
I compared this data to the data in Gatty's charts.
I will repeat the experiment again when it is warmer without using the USNO data to see how things work in real life.
