After two Chinese Culture University (CCU) professors recorded what they claim is the longest-lasting rainbow in history on November 30, their department has launched a campaign to apply for recognition by Guinness World Records with the use of a "rainbow clock" to verify every second of the 9-hour-long rainbow's existence.

It was spotted by students and professors at the Chinese Culture University in Taipei, capital city of the Chinese state of Taiwan.

"It was incredible... It felt like a gift from the sky".

Taiwan News reported that if this timing was confirmed, it would break the previous record of six hours for the longest-lasting rainbow at Yorkshire, England on Mar 14, 1994. "It happens so rarely", said Professor of atmospheric Sciences University of Chu Xuan kun.

Chou and a second professor, Liu Ching-huang, led the efforts to document the rainbow with the help of the department's students and the campus community.

Thursday's rainbow clocked in at eight hours and 58 minutes.

The natural marvel didn't catch the department wholly by surprise: There was a nearly-six hour rainbow the previous week.

And there was not just one, but four - two primary and two supernumerary - rainbows, according to Chou.

The rainbow was recorded by two scientists at Chinese Culture University in Taipei.

A northeastern monsoon, which trapped moisture in the air and created clouds, along with sunlight and slower wind speeds set the stage for spectacle.

To apply for Guinness World Record's "longest-lasting rainbow", the professors are gathering more evidence from those who witnessed the unusual phenomenon on campus that day.

Such atmospheric conditions are common in winter in Taipei's Yangmingshan mountain range, where the campus is located, making it an ideal place for spotting long-lasting rainbows, Chou said.

Rainbows typically last much less than an hour, according to the Guinness website.
