Wikipedia definition
3. OccultationAn 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 an object in the background. In this general sense, occultation applies to the visual scene observed from low-flying aircraft wherein foreground objects obscure distant dynamically, as the scene changes over time.
