Two Supermoons Will Light Up Night Sky This Month

The first supermoon, known as the Sturgeon Moon, appeared on August 1st and shone brighter than average.
Another supermoon, called a blue moon, will occur on August 30th and be an even closer perigee full moon.
Supermoons happen when a full moon coincides with the moon's closest approach to Earth in its orbit.
These two supermoons in August are a rare event that won't occur again until 2037.
The supermoons provide a great opportunity for moon observation and astrophotography.
