celestial event

(generally something happening visible in the sky)

The phrase celestial event in astronomy refers to something happening visible in the sky. It is typically used to refer to predictable events such as an eclipse, for example, in the title of a calendar or of a portion of an almanac. Other examples: an occultation, a conjunction, an opposition, a solstice, a particular (monthly) phase of the Moon, or a meteor shower.
