Lunar Phase

Full Moon

The Full Moon occurs when the Moon stands in exact opposition to the Sun, achieving maximum illumination and maximum separation. Classical astrology regards this as the Moon's moment of greatest light and power, yet also a moment of tension, as the opposition is an aspect of polarity, awareness, and confrontation between the solar and lunar principles.

The Full Moon is the lunar cycle's peak - the moment when the Moon stands directly opposite the Sun and reflects its maximum light toward the Earth. For classical astrologers, this is simultaneously the Moon's strongest and most complex condition: fully lit and therefore fully expressed, but in opposition to the very source of its light.

In classical doctrine, the opposition is not simply good or bad. It is an aspect of perfect separation and full awareness. The Moon at opposition has completed its first half-cycle from the Sun and reached the furthest point it will achieve before beginning its return. What was hidden at the New Moon is now fully visible.

The Full Moon was used in classical astrology as a timing marker, a point of culmination in electional work, and a moment of heightened lunar influence in mundane and natal interpretation. The exact degree and sign of each Full Moon carries the combined weight of both solar and lunar signification.

The Opposition in Classical Doctrine

The opposition (180 deg) is one of the five major Ptolemaic aspects. Classical doctrine treats it as an aspect of awareness, confrontation, and completion - matters come fully to light, but the two planets involved pull in opposite directions. At the Full Moon, the Sun and Moon are at maximum distance, each fully expressing their contrary natures.

Peak Illumination and Power

The Full Moon is the Moon's most powerful condition in terms of light. A fully lit Moon is visible all night, rises at sunset, and sets at sunrise. In classical electional astrology, while the Moon's waning status (it will now decrease in light) is a consideration, the Full Moon itself represents maximum lunar expression and is favorable for matters requiring visibility, completion, and full engagement.

Elections and the Full Moon

Classical electional doctrine is nuanced about the Full Moon. It is powerful but marks the beginning of the Moon's decrease in light. Matters requiring public visibility, culmination, or the bringing-to-light of hidden things are more naturally suited to Full Moon elections than quiet private beginnings.

Full Moon FAQ

What does the Full Moon mean in classical astrology?

In classical astrology, the Full Moon is the Moon at opposition to the Sun - maximum light, maximum separation, and maximum lunar expression. It is a peak of power and visibility. The opposition aspect also brings awareness and confrontation: what was hidden becomes visible. After the Full Moon, the Moon begins to decrease in light.

Is the Full Moon good or bad in astrology?

Classical astrology treats the Full Moon as powerful but complex. The Moon is at maximum light and expression - very strong. But the opposition aspect introduces tension between solar and lunar principles, and the Moon is about to begin decreasing in light. Full Moon elections favor completion, visibility, and culmination rather than quiet new beginnings.

What is the difference between the Full Moon and New Moon in astrology?

The New Moon is the Moon's weakest condition - combust at conjunction with the Sun, without light. The Full Moon is the Moon's strongest light condition - fully illuminated, at maximum separation. New Moons favor hidden beginnings; Full Moons favor visible culminations. Classical doctrine uses both as timing markers in elections and mundane charts.

What sign is the Full Moon in?

Because the Full Moon is by definition opposite the Sun, it always falls in the sign opposite the Sun's current position. When the Sun is in Aries, the Full Moon falls in Libra. When the Sun is in Scorpio, the Full Moon falls in Taurus. The sign colors the Full Moon's signification and determines the dignity of the Moon in that placement.
