If you think about the rotation of the earth and its revolution around the Sun, you will see that is the time when the atmosphere above you is ploughing into the dust stream. In theory, the best time would be during the first half of the day - pity it's a bit bright then.
During the early evening, much of the earth is between you and the "oncoming" dust stream.
