May's full moon on Saturday coincides with its perigee and will appear extra large in the night sky about 11:35pm.
Astronomers both professional and amateur will be treated to a special event this Saturday as the full moon appear very bright and larger than life while making its perigee, or closest approach to earth. This is just one of the six celestial events that will happen in May.
Some of the best time to view the moon will be the early evening, just after the moon rises. Catching a partially obstructed view of the moon is said to be best, as that will create an optical illusion that makes the moon seem even bigger.
