Nine-hour rainbow appears in Taiwan

Taiwan: “A gift from the sky,” exclaimed a Taiwanese professor to BBC as he caught on his camera a rainbow that lasted nearly nine hours in the mountains around Taipei on November 30. It appeared around 7.15 am and lasted till 4.43 pm Taipei time. A lack of strong wind, partially cloudy sky and moist air caused by seasonal monsoons are said to have combined to cause this phenomenon, says Chou Kun-hsuan of Chinese Culture University. His colleague Prof Liu Ching-huang and students of the Department of Atmospheric Sciences helped him in documenting this breathtaking sight. He now plans to submit it for a world record. The previous record holder was seen for six hours above Sheffield, UK, in 1994.
