The maths of twilight etc

Chap(esse)s -

You might find some of this interesting. After posing a question about
constellation rise times and time of a given sky brightness (see thread
below), I did a bit of modelling. The results are here under 'Twilight':

Comments welcome ...... (bear in mind it was done pretty quickly!)

Who said that?

No, I don't think it s something which people need seeing that they
