The Galileo spacecraft took this composite image on December 7, 1992 on its way to explore the Jupiter system in 1995-97. The color is 'enhanced' in the sense that the CCD camera is sensitive to near infrared wavelengths of light beyond human vision. (Larger image at nasa.gov)

The full moon is the phase of the moon that occurs when the Moon lies on the opposite side of Earth from the Sun. The moon as seen from the surface of the earth is fully illuminated by the sun at this time, presenting a "full" round disc to viewers on earth. As always, only half the total surface of the moon is illuminated.

A full moon is the only time when a lunar eclipse is possible; at that time the moon may move through the shadow cast by the earth. However, because of the tilt of the moon's orbit around the earth relative to the earth's orbit around the sun, the moon may pass above or below the shadow, so a lunar eclipse does not occur at every full moon. Full moons are generally a poor time to conduct astronomical observations, since the bright reflected sunlight from the moon overwhelms the dimmer light from stars.

An approximate formula for the average time of full moon N is:

D = 20.362954 + 29.5305888531 × N + 102.19 × 10-12 × N 2

where D is the number of days (and fractions) since 1 January 2000 00:00:00 TT, and N is an integer.

To obtain this day expressed in UTC (world clock time) for future events (N > 0), apply the following approximate correction:

-0.000739 - 235 × 10-12 × N 2

The true full moon may differ from this by more than 14 hours, due to periodic perturbations. The long-term error of the formula is approximately 1 × cy2 seconds in TT, and 11 × cy2 seconds in UT (cy is centuries since 2000); see the new moon page for a detailed explanation.

The age and apparent size of the full moon vary on cycle of just under 14 synodic months, which is called the full moon cycle.

Full moons are traditionally associated with insanity (hence the terms lunacy and lunatic) and with various unusual phenomena such as lycanthropyIn folklore, Lycanthropy is the ability or power of a human being to undergo transformation into an animal. The term comes from ancient Greek lykanthropos (Λυκανθρωποσ): lykos ("wolf") + anthr.

It is called Neopaganism by academics and many adherents to distinguish it from earlier forms of Paganism, from which it dif hold a monthly ritual called an EsbatWiccans and many other Pagans celebrate the esbats which are the full moons. The new moons are also celebrated by many groups, and some very dedicated groups also celebrate the first and last quarter. Traditionally, the Sabbats are times of celebration, w at each full moon.

The traditional Chinese calendarThe Chinese calendar is a lunisolar calendar formed by combining a purely lunar calendar with a solar calendar. Among Chinese, the calendar is not used for most day to day activities, but is used for the dating of holidays such as Chinese New Year (Spring is based on the phases of the moon. The full moon is always the middle of a month.
