The sun's light is now shining on the other half of the visible face of the moon. Last quarter: The moon has moved another quarter of the way around Earth, to the third quarter position. Waning gibbous: More than half of the moon's face appears to be getting sunlight, but the amount is decreasing. When they do, we have a lunar eclipse as Earth's shadow crosses the moon's face.
