[net.space] re Sirius low in sky

	The only place where Sirius is not low in the sky twice a day is
close enough to the north pole that it is never in the sky. Anything near
the horizon, Sun, Moon, planet, or star will be quite a bit more red than
at the zenith, since more little dust particles are in the light path,
reflecting blue light, and transmitting red light.
	If we are ever subjected to a vote on the unprovable point of
whether Sirius B was a red giant in recorded history, I vote no, but of
course our vote would also prove nothing. My reason, I don't want to
scrap our models for stellar evolution to agree with one word translated
from out of context.
