3月19日上午，青島、廣州、沈陽、銀川等地的天文愛好者觀測到了日偏食天象。據(jù)國家天文臺專家稱，此次日偏食持續(xù)了1個半小時，西部地區(qū)最大食分可達0.7以上，即太陽直徑的十分之七被月球遮掩。由于天氣原因，北京居民與這次天象奇觀失之交臂。

Many parts of China experienced apartial solar eclipseon Monday morning, lasting around one and a half hours, according to the China National Astronomical Observatory.

In Nanjing, east China's Jiangsu Province, the partial eclipse occurred from 9:25 a.m. to 11 a.m. on Monday, in which the moon covered about 20 percent of the sun, according to Wang Sichao, researcher with Zijinshan Astronomical Observatory under the Chinese Academy of Sciences.

Sky gazers in northeastern Jilin, central Henan, eastern Shandong Provinces and northwestern Ningxia Hui Autonomous Region also witnessed the partial eclipse.

In western China, 70 percent of the sun was eclipsed but in Beijing, however, cloudy and drizzly weather deprived enthusiasts of the chance of seeing their first partial eclipse since 1997.

"Those who missed this one will have opportunities to seetotal solar eclipseson August 1, 2008 and July 22, 2009, and a partial eclipse on January 15, 2010," Wang said.

During the last century (1901- 1999), 78 partial and 71 total solar eclipses have been reported worldwide.

Chinese astronomers are believed to have been the first to record solar eclipses more than 3,000 years ago.
