Occulation

An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer.

 

On 18 June 2007, Venus and Moon came very close in a rare alignment between 8.59 to 9.55 pm PST. This rare phenomenon called "occulation" occurs many times a year since the Moon and Venus travel on the same plane. In the above photograph, taken by me, Venus, the tiny dot to the left of a few days old moon, is a lttle away from the darker brim of the Moon, later to be occulated.
