    Re: Definition of the twilight intervals

    It seems like it can't be just a coincidence that Sky & Telescope published an online article about twilight and its variations just last weekTiptoe into the Twilight. This is one of Bob King's articles. He writes really terrific pieces about various topics in observational astronomy. I find I learn something new in almost every article of his that I read.

    And for those interested in Wikipedia issues, it will be interesting if this article is soon cited as a source on twilight definitions.
