Thanks a lot.

I am sure what you really want is the elevation (angle above the horizon) at solar noon (different from civil noon).
In that case, the declination of the Sun at the solstice is equal to the tilt of the Earth's axis (23.5 degrees). On the December solstice, it is 23.5 degrees south, in Jusne it is north. If you were on the equator, the elevation would be 23.5 degrees short of straight overhead or 90 - 23.5 = 67.5 degrees. As you move north, each debree north putd the Sun 1 degree lower to the south. At 54 degrees north then the Sun is at an elevation of 90 - 23.5 - 54 = 12.5 degrees.

The sun is North of the equator so when you look east in the morning, the angle you see makes it easy to observe that fact. If you have a globe of the earth handy, and it is mounted in a frame that applies a correct tilt to the globe, hold the globe so the north pole is tilted toward an imaginary "sun" and have that sun to your right. That represents the relative position of the Earth and sun at this time of year. With the Earth held in that position, rotate the globe so you are looking at your location on earth and the sun is located to your right (the east). That would be your location at sunrise. Looking at the lines of latitude on the globe, you will see they have a southerly tilt relative to your position and the position of the sun You LIVE north of the tropic of Capricorn (that line on a globe that denotes the limit of the sun's northern trajectory) so at noon you have to look a little south to see the sun. To prove thet, again rotate the globe (90 degrees) so your location is now looking almost straight up at the sun. Your location will be a bit north of the tropic of Capricorn which is where you would be standing if the sun were straight up.. So you are looking slightly south.

That would be the first day of winter. The angle of the sun at noon on that day would be
(90 - 54) - 23.5 = 36 - 23.5 = 12.5°

Sounds like a trigonometry question...but you could just use an analemma instead.
