"Sturgeon Supermoon Shines Bright in Global Skies"

The "sturgeon moon," a supermoon that appeared about 8 percent bigger and 16 percent brighter than an average moon, delighted skywatchers worldwide on Tuesday night. Supermoons occur when the moon is closest to Earth in its orbit. The August moon is called the sturgeon moon because it coincides with the spawning season of North America's largest freshwater fish. The supermoon was technically 100 percent full at 2:32 p.m. Eastern time on Tuesday, but became visible in the evening. Skywatchers can look forward to another supermoon, a super blue moon, on August 30, which is a rare event that won't happen again until 2037.
