Howdy all;
I am going to bring up a discussion from the late Issac Asimov. He said that Sirius was most important when it was rising before the Sun in the morning sky. This helical rising marked the flooding of the Nile and other important religious times in the ancient Middle East.
So, we all know that a rising star is shining through a lot of dust in the air. He believed it was reddened by that dust pollution and that when it was in its most important position in the sky to the ancients it was indeed ruddy.
It is an interesting solution;
Steve Coe
