The Waning Gibbous phase is the sixth phase of the Moon's cycle and is the phase after the Full Moon. During this phase, the illuminated portion of the Moon's visible surface decreases from 96% to 71% as the Moon moves away from the Sun.
This phase usually lasts for about four days, and during this phase, the moon is said to be in the "gibbous phase".
