Why does sun appear elliptical during sunset and sunrise?
I have read that when the Sun (or Moon) is near the horizon, the rays from the lower edge are bent more than the rays from the upper edge. This produces a shortening of the vertical diameter, causing the Sun to appear elliptical
BUT i don't understand why the rays from lower edge are more bent due to refraction.
