The sun dipped behind the horizon, the boat went on.
She pulled away from me once the sun had dipped below the horizon.
The sun had dipped below the west wall and there were only a few minutes of light left.
The sun had dipped behind the trees across the avenue.
The sun had dipped below the horizon when he turned and walked down.
As she spoke the sun dipped, and the cold shadow suddenly fell on us.
The sun was dipping low enough so that they were much of the time in shadows.
Then the sun dipped low and they all had the same other place to be.
The sun does dip below the horizon for about an hour.
As the sun dipped toward the horizon they pushed out and got under way.
