Snowman9000, that is an interesting table. You can see what I was saying for here that "high noon" or meridian passage (they aren't quite at the same time but ignore that for this work) is between 1300 and 1330 when the sun is bearing 180 (South)
The angles work for the afternoon being a mirror image of the morning, but of course, in real life the afternoon sky isn't the same as the morning sky for how much sun you get. Often there is a morning haze that takes some time to "burn off" or some other difference.
ALSO-- I need to review my "8 degrees a month change of tilt" based on that altitude of 60.7ish for 15 May. That means Dec was about 19N close to about 23N for 21 June, and up from zero on 21 March. So Dec change can't be linear, which I never noticed before (no reason to notice that!)
