Do you have any explanation (maybe astronomical) to the fact that in the west side where sunsets, the lower part is darker that the upper part (after sunset)? I'd think that the lower part of the west should have more light than other parts of the sky until end of Ben Hashmashot.
Thanks in advance.

I asked Dr. J. Shamroth, who suggested that due to the considerably larger amount of additional visual haze and atmospheric dust through which one looks when he gazes at the light above the horizon (where the atmosphere is thicker, from our perspective), the sunlight there appears darker than the light higher up in the sky which is not obstructed by nearly as much atmospheric dust.
