Thanks, however note that the definition of nautical twilight in the text and in the diagram (from Wikipedia) are not consistent with each other.

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.
