Hi
Rising, transit and setting is my next function... This is a difficult one. When I do it last year on Mathematica I use the interpolation. The problem is that the time for the three moments are not always in the same cycle for the object. The Sun is not a problem because it always rise in the morning. But a planet can rise at 23 hours and set a 7 hours the next day. In that case the program will not calculate these two moment because the occur at two differents days. Here the user must understand this concept.
