Question

An annularity(日环食) is expected to cross China Friday afternoon, a researcher with the Purple Mountain Observatory under the Chinese Academy of Sciences said Wednesday.

The phenomenon, predicted to be the longest annularity of the next 1,000 years, can be seen in some areas of Yunnan, Sichuan, Guizhou, Shaanxi, Hunan,  Hubei,  Henan, Anhui, Jiangsu and Shandong provinces as well as Chongqing.

A partial eclipse(日偏食) would be seen in most of the rest of China, except for the northeast tip of Heilongjiang Province, said Cheng.

According to the National Aeronautics and Space Administration (NASA) of the United States, the annularity will begin in Africa and pass through the Indian Ocean, where the maximum duration(持续的时间) of annularity will reach 11 minutes and 8 seconds.

It will continue into Asia through Bangladesh, India, Myanmar and China. Cheng said the annularity will end at Jiaodong peninsula in Shandong Province, China.

The longest duration of the annularity on China’s territory would be 8 minutes and 17 seconds in Ruili, Yunan Province. A sunset with the annularity would be seen in some areas of Shandong, Guangdong and Taiwan, said Cheng.

An annularity occurs when the moon does not cover the entire disc of the sun so that a ring of light encircles the shadow of the moon.
