Flights to feature rare supermoon

As Mid-Autumn Festival approaches - this year celebrated on Sept 27 - bookings for moon-viewing flights have soared, according to a travel service provider.

Moon-viewing flights are flights that depart between 6 pm and 12 am from Sept 26 to 28. During the journey, tourists can enjoy the moonlight. This year is expected to be special, as during the three-day festival both a supermoon and a lunar eclipse will be visible in China.

A supermoon occurs when the moon comes closest to earth. The diameter will appear 14 percent larger than normal. According to NASA, the United States space agency, a supermoon is very rare. Last time a supermoon and lunar eclipse occurred near one another was more than 30 years ago. The next convergence will be in 2033.
