Full Moon
Next occurrence (UTC):
Typical illumination: 100%
A full moon occurs when Earth is roughly between the Sun and the Moon. The entire Earth-facing hemisphere is sunlit — illumination is near 100%.
How it looks
The disk looks round and bright. Contrast is lower than at quarter phases because there are few shadows; the Moon can wash out fainter stars.
When it is visible
Full moon rises near sunset, stays up all night, and sets near sunrise. It is the brightest night-time moon and the phase people most often notice.
Geometry
Phase longitude is near 180° (opposition). When the alignment is precise and the Moon is near a node, a lunar eclipse can occur.
