Waning Gibbous Moon: This intermediate Moon phase starts after the Full Moon and lasts until half of the Moon’s face remains lit up in the Third Quarter.
The Waning Gibbous phase is when the lit-up part of the Moon shrinks from 99.9% to 50.1%. It starts just after Full Moon and lasts until the Third Quarter Moon.
Waning means that it is shrinking and getting smaller, while gibbous refers to the oval-to-round shape.
It can be challenging to differentiate the first stage of a Waning Gibbous from a Full Moon when 98%-99% of the surface is illuminated.
The orientation of the Waning Gibbous Moon depends on the time, the date, your location, and the Moon’s position in the sky. Exactly which part of the Moon is lit up—the top, bottom, or the side—also depends on how high the Moon is in the sky. (*Source: timeanddate.com)
