Extra supermoon' makes appearance after typhoon

Hours after Typhoon No. 11 petered out, the night skies cleared to reveal a rare lunar phenomenon known as "extra supermoon."
This occurs when the moon is closest to the Earth during its elliptical orbit and coincides with a new or full moon phase.
NASA called the Aug. 11 event an "extra supermoon" because the full moon was at its zenith in the same hour that it was at its closet point to the Earth, an even rarer occurrence.
As the clouds began to part over Fukuoka's Chuo Ward, moonlight cast a glow over the city just before 3 a.m.
The next supermoon will occur Sept. 9, the day after Japanese harvest moon viewing celebrations.
