Phases of The Moon
</dt>
The various appearances of the moon during different parts of the synodical
month.
</dd>
The cycle begins with new moon or change of the moon at conjunction.
The visible part of the waxing moon increases in size during the first half of
the cycle until full moon appears at opposition,
after which the visible part of the waning moon decreases for the remainder of
the cycle. First quarter occurs when the waxing moon is at east quadrature;
last quarter when the waning moon is at west quadrature. From last quarter to
new and from new to first quarter, the moon is crescent; from first quarter to
full and from full to last quarter, it is gibbous. The
elapsed time, usually expressed in days since the last new moon, is called age
of the moon. [[/a>|/a>
