That's called the "Third Quarter" phase. It occurs
about 22 days after the New Moon.
The moon phase when none of the lighted portion can be seen from Earth is called a new moon. During this phase, the moon is positioned between the Earth and the Sun, so the side of the moon facing Earth is not illuminated.
"Waning" means that less and less of the moon's lighted side is visible from Earth as time goes on. That's what's happening during the entire two weeks from Full Moon until the next New Moon.
Not exactly. The lighted side of the moon as seen from Earth is that part that is not shadowed by the Earth.
This is called a waning moon. If it's more than half full, it's called "waning gibbous." If it's less than half full, it's "waning crescent." The half-full moon between waning gibbous and crescent is called the last quarter. Likewise, on the "growing" side, it's called a "waxing moon" (both crescent and gibbous) and the first quarter, respectively.
It is called a crescent, and if it is growing, it's called a waxing crescent, otherwise, it's a waning crescent. So, when less than half is facing the earth, it is called a Waning Cresent
This phase is called a waning moon and occurs as the moon transitions from a full moon to a new moon. The decrease is a result of the changing position of the moon in relation to the sun and Earth.
The moon is in its waning phase when less and less of the side facing the earth is lighted. This phase occurs after the full moon and leads up to the new moon when the side facing the earth is completely dark.
That would be Third Quarter.
The decreasing of the illuminated face of the Moon (full to new) is called "waning." (The opposite, increased illuminated area, is called waxing.)
The moon phase when none of the lighted portion can be seen from Earth is called a new moon. During this phase, the moon is positioned between the Earth and the Sun, so the side of the moon facing Earth is not illuminated.
Waxing is to get bigger and waning is to get smaller.
This period is known as the waning phase of the moon. During this phase, the illuminated portion of the moon visible from Earth decreases in size as it transitions from a full moon to a new moon.
"Waning" means that less and less of the moon's lighted side is visible from Earth as time goes on. That's what's happening during the entire two weeks from Full Moon until the next New Moon.

It is the waning phase.
