Duffet-Smith. I was able to order a copy from a local bookstore. The B. Dalton here said they stock it, but they happened to have sold them all. As far as the definition of sunset, there are lots of them. The program uses the time when the upper limb of the sun descends below the horizon. Note that it is calculated for the observer; a more accurate calculation would include your mountains. Refraction causes a sun which is already below the horizon to appear to be above. Bob Bond
