The Moon was new on December 22, and will be "waxing", or increasing, until the Full moon.
The next Full moon will be Jon January 11, 2009, and will be waning for two weeks after that.
When the illuminated portion is decreasing from one night to the next, the moon is in its 'waning' phases.
"Waxing" is growing BIGGER from one night to the next."Waning" is shrinking SMALLER from one night to the next.
When the crescent has waned all it can, we get a New Moon next.
After the full moon, the moon wanes (gets smaller) through the waning gibbous phase, to the last quarter moon, the waning crescent, and finally the new moon.
A WANING Moon. An increasing Moon is called a waxing Moon. NB From New Moon to first quarter it is a WAXING CRESCENT Moon From 1sr Quarter to Full Moon it is a WAXING GIBBOUS Moon From Full Moon to Last Quarter it is a WANING GIBBOUS Moon From Last Quarter to next New Moon it is a WANING CRESCENT Moon.
A "shrinking moon" refers to the phenomenon where the moon appears to be decreasing in size, usually during its waning phase. This is a natural occurrence as the illuminated portion of the moon visible from Earth decreases over the course of the lunar cycle.
The next moon phase after the third quarter moon is the waning crescent moon. It is characterized by a decreasing illuminated portion of the moon visible from Earth.
The moon phases from a new moon to a full moon is known as waxing. The moon phases from full moon to the next new moon is waning.
The moon is waning when it is getting smaller
Waning gibbous, Third Quarter and Waning Crescent are the 'waning' moon phases.
The right half of the moon is illuminated.
The Moon appears to be waxing when it is transitioning from a new moon to a full moon, and waning when transitioning from a full moon to a new moon. Without specific information on the current lunar phase, it's not possible to determine if the Moon is waxing or waning at this moment.
