Position Data Search Based On An Object Name. | Solar Position: Calculator. Below is an interactive tool for calculating the azimuth and altitude of the Sun at any date and time. Your first step in the use of this tool is to set the Latitude and Longitude of the desired location - making sure to first set the TimeZone value as this will make entering the longitude easier. In addition to the current Sun position, it also calculates Sunrise / Sunset times, the Declination and Equation of Time as well as the relative shadow length. To enter a value manually, remember to hit the Enter key. Figure 1 - An interactive solar position calculator with additional information such as the Declination and Equation of Time as well as the relative shadow length for a vertical element of height h. You can actually download this as a stand-alone Windows application as part of the Teaching_Tools package. Manual Calculation Method The algorith used in the interactive tool above to determine the position of the Sun from any location on Earth is outlined below.

We assume you are converting between arcsecond and degree. You can view more details on each measurement unit:arcsecond or degree The SI derived unit for angle is the radian. 1 radian is equal to 206264.806247 arcsecond, or 57.2957795131 degree. Note that rounding errors may occur, so always check the results. A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.7×10-7) of a circle. A degree (or in full degree of arc), usually symbolized by the symbol °, is a measurement of plane angles, or of a location along a great circle of a sphere (such as the Earth or the celestial sphere), representing 1/360 of a full rotation.
