is the black spot straight down the map?

Answer 1

On a globe on an airless world, the terminator (divider between lit and unlit surface) will pass through the poles. Due to the lensing effect of our atmosphere, the sun bends "around" the globe just a bit.

Answer 2

The terminators will appear vertical.
