China is set to experience a total solar eclipse (日全食) tomorrow morning. The shadow cast by the Moon will track across China from West to East, allowing viewers in Tibet, Yunnan, Sichuan, Chongqing, Hubei, Hunan, Jiangxi, Jiangsu, Shanghai and Zhejiang to observe totality. This total eclipse has the longest duration of any in the 21st century, and is likely to be the one observable by the most people.
To see the total eclipse in Yunnan, you'll need to be North of Diqing, near to Yunnan's border with Tibet or Sichuan. Viewers there can expect around four and a half minutes of totality, starting at around 9am Beijing time. In downtown Kunming, there'll be no total eclipse, but the partial eclipse (日偏食) will reach around 85% obscuration at around 9:08am.
