What are they?

An occultation occurs when one celestial body passes in front of another.
These frequent and intriguing events are fun to watch, and provide an important way for amateur astronomers to make significant discoveries about objects within our own Solar System as well as the stars beyond. The exact time of an occultation, and its duration, will depend upon the observer’s latitude and longitude.
