The moon will officially become full at 11:35PM on Saturday, May 5. This coincides almost perfectly with the moon's perigee — that is, the moment when the moon is closest to Earth in its orbit. This supermoon will be especially pronounced given that this will be the moon's closest approach of the year.
There's no need to get the kids out of bed for this one — 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.
The supermoon will have an effect on tides, though experts say there's no need for alarm since the increased effect is still relatively weak. That's not to say a supermoon hasn't caused damage in the past: It's believed that a supermoon event may have contributed to the sinking of the Titanic 100 years ago.
