In this July 1997 still frame captured from video, the bright star Aldebaran has just reappeared on the dark limb of the waning crescent moon in this predawn occultation.

An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer. The word is used in astronomy (see below). It can also refer to any situation wherein 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 (or computer-generated imagery) wherein foreground objects obscure distant objects dynamically, as the scene changes over time.
