The horizontal line in the middle is the Celestial Equator.

Imagine that we are standing on the celestial equator (the horizontal line in the middle). The horizon moves toward the left as shown in the pictures below. Study them carefully and notice how the horizon moves as we observe its motion from the celestial equator.
In this final picture, the horizon has moved back to its original position
in one day.
