Regulus Occultation

When the moon, in its monthly travel around Earth, moves across a bright star, it is called an occultation.  On this date, the moon is moving toward the bright star Regulus.  Here is a superposed series of pictures taken over 1 hour as Regulus apparently “approaches” and then is eclipsed by the moon.
