This event is a rare astronomical phenomenon in which the Moon passes in front of a brighter celestial body, such as a star, and temporarily blocks its light. During an occultation of the Moon, the Moon will appear to be larger than normal, and the star will appear to be dimmer
An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks from view (occults) an object in the background. In this general sense, occultation applies to the visual scene observed from low-flying aircraft when foreground objects obscure distant objects dynamically, as the scene changes over time.
