Answer:
Waning
Explanation:
The lunar phase that occurs after the Waning Gibbous is called the waning. The waning moon is characterized by the stage at which the visible portion of the moon gradually becomes smaller - until it seems to disappear completely in the night sky, starting the lunar cycle again with the New Moon. When the moon is in the waning phase the whole world sees the same phase. But not in the same way. An observer in the southern hemisphere sees the moon as a letter "D." At that very moment, the moon seen from the northern hemisphere will resemble the letter "C", ie the inverted image seen by the observer from the opposite hemisphere.
