Rare "super blue moon" lights up night skies worldwide for 3 days

A supermoon is a phenomenon in which the Moon is closer to Earth than at other times, making the full moon larger and clearer than usual, and can be clearly observed with the naked eye. The super blue moon that appeared on August 19 is also known as the "sturgeon" moon.

This month's full moon is also called a super blue moon, a combination of two phenomena: a super moon (a full moon) and a blue moon (a full moon occurring twice in a calendar month or three times in four months). Normally, there are only three full moons in each season; however, because the full moon cycle occurs every 29.53 days, there will occasionally be four full moons in a season. The extra full moon in a season is called a blue moon; it occurs on average every 2.7 years.
