solstice, when its value is the negative of the axial tilt. This variation produces the seasons. A line graph of the Sun's declination during a year resembles...

declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the...

of the observer on the Earth; δ {\displaystyle \delta } is the sun declination. The Earth rotates at an angular velocity of 15°/hour. Therefore, the expression...
