Summary

The report presents graphs of local hour angle vs solar depression angles from 0 to 32 degrees for latitudes 0 to 90 degrees. Similar graphs are given in the Air Almanac for solar depression angles to 12 degrees, allowing computations of sunrise to sunset and twilight phenomena up to altitudes of approximately 100 kilometers. The graphs given in this report extend the altitude range of such computations to approximately 1000 kilometers. The tables can also be used for planets and stars, but for the moon considerable error will arise unless corrections for parallax are applied. (Author).
