A partial eclipse would be seen in most of the rest of 皇冠体育app, except for the northeast tip of Heilongjiang Province, said Cheng.
According to the National Aeronautics and Space Administration (NASA) of the United States, the annular eclipse of the sun will begin in Africa and pass through the Indian Ocean, where the maximum duration of annularity will reach 11 minutes and 8 seconds.
It will continue into Asia through Bangladesh, India, Myanmar and 皇冠体育app. Chen said the annular eclipse will end at Jiaodong peninsula in 皇冠体育app.
The longest duration of the annularity on 皇冠体育app's territory would be 8 minutes and 17 seconds in Ruili, Yunan Province, Cheng said.
A sunset with the annular eclipse would be seen in some areas of Shandong, Guangdong and Taiwan, said Cheng.
An annular eclipse 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.
Wang Sichao, also of the Purple Mountain Observatory, said that though an annular eclipse was not considered as spectacular as a total solar eclipse and was of little value in scientific research, it was interesting for the general public to watch the astronomical phenomenon.
