| Information about the eclipse 是次日食資料 |
Saros 136 is back - this total solar eclipse will be the longest in the 21st century, with totality lasting slightly more than 6.5 minutes at the point of maximum eclipse.
On July 22nd 2009, a central total solar eclipse will be visible within a narrow path along eastern Asia, extending into the Pacific Ocean. The umbral shadow of the moon will strike Earth shortly before 01 UTC near western India, and the shadow will then move across parts of Bangladesh, Bhutan and into China at about 01:10 UTC. It will leave the Asian landmass via Shanghai at 01:40 UTC and make its way into the Pacific Ocean. Northern parts of the Ryukyu Islands will be able to enjoy a total eclipse shortly before 02 UTC and a couple of Islands in the Pacific Ocean, including Marshall Islands, will experience totality one to two hours later. The shadow will finally leave the planet east of the international date line at about 04:20 UTC when the sun there dips below the horizon.
Apart from the path of totality, a much wider range of areas will be able to experience partial eclipse of different degrees. The whole of SE Asia, central Asia as north as Mongolia and southern Russia, Japan, Philippines and northern Indonesia will be under the penumbral shadow. The fact that the whole China and most parts of India are under the moon's shadow signifies that this may well be one of the eclipses viewed by the greatest number of people in the world.
It is worth noting that Saros 136 is one of the most enjoyable (solar) eclipse families in this era; it is famous for producing very long total eclipses which are visible to many people as a result of its proximity to the equator. For instance, the following notable (total) eclipses in the last century are all from the Saros 136 family:
- 20th June 1955 --- longest in the 20th century with a duration of 7 minutes and 8 seconds (Hong Kong experienced a partial eclipse of magnitude 0.793 near 1 p.m. that day [under Hong Kong Summer Time]);
- 30th June 1973 --- visible in almost the whole Africa; duration of totality at greatest point of eclipse reached 7 minutes and 3 seconds;
- 11th July 1991 --- viewed by millions of American and people living in central America; totality duration 6 minutes and 53 seconds.
The famous observation that gave evidence to Einstein's general theory of relativity was also made during a Saros 136 eclipse (29th May 1919) (more info).
沙羅週期 136 的日食將於 2009 年重臨地球。本年 7 月 22 日的日食將為本世紀裡最長的全食，最大食分處之全食時間超過 6.5 分鐘。
當天月球的本影區將於約 01 UTC (世界協調時) 到達印度西面，繼而由西向東移至孟加拉、不丹，並於 01:10 UTC 進入中國。本影區橫越中國中南部後將於 01:40 UTC 經過上海，並進入太平洋。琉球群島北面可於 02 UTC 前見到全食，而全食區將於一兩小時後到達太平洋中部分島嶼，如馬紹爾群島。月球本影區將於約 04:20 UTC 在國際換日線以東離開地球，結束整個全食過程。
全食帶外的大範圍地區將可見到一次不同程度的日偏食，包括整個亞洲東南部、亞洲中部 (北至蒙古和俄羅斯南端)、日本、菲律賓和印尼北部。由於整個中國和印度大部分地區均在月球的影子下，預料本次日食將會為其中一個最多人觀看之天文現象。
值得留意沙羅週期 136 於近代製造了不少嘆為驚人的日食 --- 它們都是以全食時間長而全食帶經過人口稠密的地區而見稱。例子有 :
- 1955 年 6 月 20 日之日全食 --- 為 20 世紀裡最長的全食 (達 7 分 8 秒)；當時香港於夏令時間下午約 1 時曾出現一次食分達 0.793 之日偏食；
- 1973 年 6 月 30 日之日全食 --- 幾乎全非洲可見日食；最長全食時間為 7 分 3 秒；
- 1991 年 7 月 11 日之日全食 --- 北美洲南部，中美洲和南美洲北部可見全食，最長全食時間為 6 分 53 秒。
沙羅週期 136 於 1919 年的日全食亦為愛因斯坦的廣義相對論提供了一個證據 (1919 年 5 月 29 日) (更多資訊)。

| Location 位置 | 24°12.6' N, 144°06.4' E (in NW Pacific Ocean 在西北太平洋) |
| Time 時間 | 02:35:21 UTC / 10:35:21 HKT |
| Magnitude 食分 | 1.0799 |

| Solar Altitude and Azimuth 該位置的太陽高度和方位角 | Altitude 高度: 85.9° ; Azimuth 方位角: 197.6° (S 南) |
Note that unlike lunar eclipse, not all places experience these times as the moon moves across the sky (and so does its shadow). They serve to show the times at which there exists at least a location on Earth that can experience those events.
不同於月食，由於月球和它的影子在地球上不是靜止不動，不同的地方將於不同的時間見到日食。以上的一般性資料只提供在地球上有起碼一點可看到那些事件的時間。
| Local (HK) circumstances 本地 (香港) 情況 |
Hong Kong will be able to experience a significant partial eclipse in the morning of that day, the magnitude of which will be the biggest since the annular eclipse on 1958 Apr 19. As the level of obscuration is relatively large, even people that are not aware of this event will notice a decrease in brightness of the sky. However notice that the sky will not turn dark, which requires more than 90 to 95 percent of the diameter being obscured.
香港將可於當天早上看到一次食分頗大的日偏食，其食分將會是自 1958 年 4 月 19 日的日環食以來最大的。由於太陽大部分被食去，即使不知道有這次日食的人亦會感覺到天空光度減低；但由於食分未達 0.9，天空不會變得非常暗:
The details are summarized in the following table:
