Link below please note "Star rising with the Sun or being in other Conspicuous positions to it".....this is important to the next thread section involving the Gregorian reform in 1582, that i will start tomorrow, with accurate astronomy pictures of the sky...as i am a very good astronomer with many astronomy programmes to prove my point!
