This year's September 27 marks three important lunar events -- a supermoon, a total lunar eclipse and Asia's Mid-Autumn Festival, also known as the Moon Festival.
The Moon Festival falls on the 15th day of the eighth lunar month.
In China and parts of Asia it's believed to be the day with the brightest moon of the year.
It's also the first time in more than 30 years that a supermoon and a total lunar eclipse are happening on the same day.
To welcome the day, companies in China are introducing a range of "moon-viewing flights."
