noun
- A bright spot that appears on a lunar halo, caused by the refraction of moonlight through ice crystals in the atmosphere; a mock moon.
Usage: Also called a mock moon or lunar parhelion.; Plural: paraselenes or paraselena.
Examples
- On a cold winter night, the astronomer observed a paraselene glowing beside the full moon.
- The paraselene appeared as a faint luminous spot within the lunar halo.
