Estimating the declination angle is necessary to determine the solar elevation. The solar declination angle reaches a maximum on June 20th (or 21st). A star's direction remains nearly fixed due to its vast distance, but its right ascension and declination do change gradually due to precession of the equinoxes and proper motion, and cyclically due to annual parallax. Similarly, when the southern hemisphere is tilted toward the Sun, it is summer in the south and winter in the north. Solar declination is defined as the angle between the Suns rays and the equatorial plane. - In-The-Sky.org. It comes from the same root as the words incline ("bend foward") and recline ("bend backward").[2]. While, from October to March, seasonal optimal tilt angles vary between 15 0 to 23 0 . For easy daily reference, the tables display the monthly declinations in Standard Greenwich Mean Time at Midnight. The solstices mark when the subsolar point reaches its northernmost and southernmost latitudes. its solar radiation data is of great importance for study of development of weather system during the year. more negative) than 90 (where is always a negative number for southern latitudes). However, the Earths orbit around the Sun is not perfectly circular it is actually elliptical. Then after a period of six months, winter will come in the north and summer will brighten up the south.
