     NANJING, June 13, 2009 (Xinhua)-China will see the longest total solar eclipse (日食) in 500 years on
July 22, a scientist said Saturday.
     The most important time of the total eclipse was expected
to begin from 9:00 a.m. to 9:38 a.m. (Beijing Time), said
Wang Sichao, a research fellow with the Nanjing-based
Purple Mountain Observatory under the Chinese Academy of
Sciences. "The total eclipse will last up to six minutes, which
is the longest one that can be seen in China in almost 500 years
from 1814 to 2309," Wang said.
     He said viewers in parts of eleven provinces in China's southwestern, central-southern and eastern areas,
such as Tibet, Hunan and Jiangsu, will be able to witness the total solar eclipse, while in most parts of Shanghai,
viewers can also see the fantastic phenomenon. For viewers in other provinces, including Beijing, they can
observe a part of the eclipse, he said.
     A solar eclipse occurs when the moon is caught between the sun and the earth while each of them moves
along their fixed orbits. In a total solar eclipse, the sun, the moon and the earth are directly in a line as the sun
swings into the shadow cast by the moon.
     Wang said the next total solar eclipse that can be seen in China will fall on March the 20th, 2034. "But it can
only be seen in-remote provinces, such as Tibet and Qinghai. It cannot not be compared with the upcoming one-
in terms of time of lasting and number of cities that can see the eclipse," he added. The last total solar eclipse
visible in China took place on the first of August last year. It was observed in northwest China and lasted two
minutes in Yiwu County of north-western Xinjiang, the best place to see the phenomenon.
