Abstract : Graphs are presented which allow the angle of elevation or depression and the true azimuth of the sun to be computed to within an accuracy of approximately 1 degree at any latitude and time of year. Alternately, the time at which the sun is at a given position can be computed within approximately 2 min. The graphs can also be used for planets and stars with declinations of less than 30 degrees. For the moon, significant errors will arise unless parallax corrections are applied. (Author)
