For theoretical 24 light hours tower height? I am not sure that the meridian will be seen from space (in the same plane and omiiting the phenomena of changing light trajectory, etc.) due to meeting the tower on the way of photons.
I do not have an unambiguous answer because there are phenomena...
The Earth rotates around its own axis within 24 hours. Theoretically, if at the equator perform a tower with a height - H, ignoring its effect on the slowdown of the Earth's rotation (we assume that the material of low density), objects and other complications, at a certain height, the linear...
