What is the angle between the sun at 35 degrees north latitude and the horizon in the early winter season in the northern hemisphere?

From June 1 day to June 2 1 day, the direct point of the sun moved northward, the sunrise gradually advanced, and the sun height gradually increased at the same time during the day; After June 2 1 year, the direct point of the sun moved south, the sunrise was gradually delayed, and the sun height gradually became lower at the same time during the day. The direct point of the sun moves north or south every day 15.6 minutes (latitude 1 equals 60 minutes). On September 23, the sun in early autumn hit the equator directly. When the beginning of winter season (1 1.7) moves southward to about 1 1.42 minutes, the solar altitude angle (the angle between the sun and the horizon) at 35 degrees north latitude is 90 degrees minus 35 degrees, while1/kloc-0 is negative.
