I don't believe the horizon proximity illusion is related to the refraction effects. However, your refraction eclipse timing distortions are very interesting. -ajb

In today's explanation of the "incomplete" solar eclipse it says "..the Moon's apparent size was too small to completely cover the Sun..". I just watched a great doumentary on Einstein which covered the decisive "proof" of the validity of his Relativity theory and accur...
