Formally known as perigee, the "supermoon" is the coincidence of the moon in its full or new phase while making its closest approach to the Earth. This creates the illusion of a brighter and bigger than normal moon, commonly known as the "supermoon". Perigee will happen on Sunday, August 10th (and again on September 9th).

Although its name hints to it being a rare occurrence, it actually occurs roughly every 13 months and 18 days. The best time to observe the "supermoon" is when its near the horizon. This creates the illusion of making the moon look even more unusually large and bright.

On Sunday evening, take a walk outside and look up at the sky. Can you see the perigean full moon?
