    Re: Basics of computing sunrise/sunset

    Hi Jim

     

    Sure, you are absolutely correct!  In situations where there is confusion, it is sometimes helpful to switch some numbers around until the problem becomes evident. 

     

    Since the only differences between the various versions of twilight and sunset are simply the altitude (albeit negative), I thought it would be a good idea for it to be tried.

     

    Best Regards

    Brad

    I think you were referring to the different definitions of twilight.
