日偏食是什麼?
當月亮運行至太陽和地球之間時,月球完全或部分阻擋太陽,便會發生日食。日環食發生時,月亮和太陽是完全一致,但由於月亮的外觀尺寸略小於太陽,造成了非常明亮的環,圍繞再月球黑暗的輪廓。這個星期天的日環食可以在亞洲,太平洋和美國西部觀看得到,不過在洛杉磯看到的日食,由於月亮不會集中在太陽正中,所以大家看到的是日偏食。


What is a partial solar eclipse?   

As seen from Earth, a Solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially blocks the Sun. From selected locations in Asia, the Pacific Ocean, the Western U.S., this will be an annular eclipse. An annular eclipse occurs when the Moon and Sun are exactly in line, but the apparent size of the Moon is slightly smaller than the apparent size of the Sun, causing a very bright ring or annulus, surrounding the dark outline of the Moon. On May 20, 2012 in Los Angeles, the eclipse will not be centered on the Sun, and is thus a partial eclipse.               

 

怎樣才能安全地觀看日食?

無論任何情況下都不應該以肉眼直接看太陽,而必須使用安裝來適當的濾鏡的望遠鏡。天文台的所有望遠鏡都配備適當的濾鏡,方便大家使用。


How can I safely view the eclipse?          

NO ONE SHOULD EVER LOOK DIRECTLY AT THE SUN WITHOUT PROPER PROTECTION. In order to view the Sun safely during the eclipse, all telescopes and other viewing should be done with certifiably safe filters. The telescopes available for free viewing of the eclipse at Griffith Observatory will be equipped with proper filters. Griffith Observatory's Stellar Emporium gift shop will stock official Griffith Observatory Solarama viewing filters and Griffith Observatory Eclipse Glasses for purchase.

Where else will the eclipse be visible?   

 

From Los Angeles, the eclipse is partial with 85.9 percent of the Sun’s diameter and 78.6 percent of the Sun’s area obscured by the Moon at maximum, the most extensive solar eclipse in L.A. since 1992 .The eclipse is annular along a path that stretches across China, southern Japan, and the north Pacific Ocean before reaching the northwest coast of the United States, There, the 200 mile-wide path crosses southern Oregon and Northern California, Nevada, Utah, New Mexico, Arizona, Utah, and finally Texas, where annularity occurs at sunset. A detailed, interactive map of the eclipse is available on NASA’s eclipse website, http://eclipse.gsfc.nasa.gov
