We here give the necessary formulae to calculate the Sun's horizontal coordinates (azimuth and altitude) for a given instant and location. As this represents a rather lengthy calculation it should be performed by a good ... In order to find the Sun's equatorial coordinates, right ascension RS and declination DS,

ESRI use this globe themselves in there ArcGlobe application, and within this app it is possible to specify a date/time and plot the sun against the globe. I wish to replicate this functionality in my application, however ESRI do not appear to have exposed this functionality in the API.
