TAIPEI - Guinness World Records is officially recognizing a rainbow recorded by a university in Taiwan as the longest-lasting on record, appearing for 8 hours, 58 minutes. The record-keeping organization announced a ceremony is being planned for Sunday at Taipei's Chinese Culture University, where professors in the Department of Atmospheric Science documented the Nov. 30, 2017, rainbow. One of the professors, Chou Kun-hsuan, said the rainbow was visible from 6:57 a.m. until 3:55 p.m., smashing the record set by a 1994 rainbow in Wetherby, England, that lasted for 6 hours. "It was amazing... It felt like a gift from the sky... It's so rare!" Chou told the BBC in December, when the university announced it was submitting evidence of the rainbow to Guinness. - Agencies
