 Information about the eclipse 是次日食資料 |
An annular solar eclipse will be visible in southern Pacific Ocean on October 2-3 local time (October 3 Hong Kong Time). The moon's antumbra will touch down on Earth near 16:50 UTC (00:50 HKT) in the central Pacific. It will then move east-southeast, turning to southeast after 17:30 UTC (01:30 HKT). The lunar shadow will reach Easter Island near 19:00 UTC (03:00 HKT), and approach southern South America near 20:20 UTC (04:20 HKT), at which point its track will turn east again. Annular eclipse on Earth ends at about 20:40 UTC (04:40 HKT) as the antumbra lifts off the Earth's surface in the southern Atlantic Ocean.
A partial eclipse is visible in the middle and southern parts of South America, Hawaii, as well as several island nations in central Pacific Ocean and parts of Antarctica.
一次日環食將於當地時間 10 月 2 至 3 日在南太平洋發生 (香港時間為 10 月 3 日)。當天，月球的偽本影將於世界協調時約 16:50 (香港時間 00:50) 到達太平洋中部並向東南偏東移動。至世界協調時約 17:30 (香港時間 01:30)，月影轉向東南，於世界協調時約 19:00 (香港時間 03:00) 抵達復活島，其後於世界協調時約 20:20 (香港時間 04:20) 抵達南美洲南部，而月影路徑屆時將東轉。偽本影區於世界協調時約 20:40 (香港時間 04:40) 在南大西洋離開地球，環食至此結束。
是次日食中，日偏食可於南美洲中南部、夏威夷、部分中太平洋島國及南極洲部分地區看到。

| Location 位置 | 21°57.2' S, 114°30.5' W (in southeastern Pacific Ocean 在東南太平洋) |
| Time 時間 | Oct 2 18:45:04 UTC / Oct 3 02:45:04 HKT |
| Magnitude 食分 | 0.9326 |
| Duration of annularity 環食持續時間 | 7' 25.1'' |
| Width of annularity 環食徑寬度 | 266.5 km 公里 |
| Solar Altitude and Azimuth 該位置的太陽高度和方位角 | Altitude 高度: 69.3° ; Azimuth 方位角: 031.1° (NNE 東北偏北) |
* Times are slightly different (a few seconds) from those indicated in the figure from NASA above due to the difference in observed and predicted values of ΔT. The current prediction of the value of ΔT on the eclipse date is 69.1 seconds.
* 由於實測及預計 ΔT 值有數秒的差距，表中所列時間與上面美國太空總署圖片中所示時間有些微差別。按照目前估計，日食日期的 ΔT 值為 69.1 秒。
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。以上的一般性資料為全球性資訊；它們並不代表某個地方的日食時間。

Notes 備註 :
- A solar eclipse always starts as partial eclipse starts or at sunrise, and always ends as partial eclipse finishes or at sunset. 日食必會於日出或初虧時開始，而於日落或復圓時結束。
- Time of maximum eclipse is not shown if an observer at that location can only see less than half of the eclipse; such places must experience maximum eclipse at sunrise or sunset. 如某地只見到少於一半日食過程，食甚時間必為日出或日落，因此不再另外顯示。
- For each time, the first line refers to local time and the second line HKT; daylight saving has been accounted for. 首行時間為當地時間 (已包含日光節約時間)；次行時間為香港時間。
- Abbreviations: "R" = Sunrise; "A" = Annular eclipse; "T" = Total eclipse; "S" = Sunset. 縮寫 : "R" = 日出; "A" = 環食; "T" = 全食; "S" = 日落。
- Central eclipse refers to totality or annularity. 中心食即全食或環食階段。

There will be two partial solar eclipses in 2025, neither of which is visible in Hong Kong. The next solar eclipse visible in Hong Kong is partial with a negligible magnitude, and will occur in July 2028.
2025 年將出現兩次日偏食，但不能於香港看到。下一次於香港可見的日食將於 2028 年 7 月出現，是一次食分甚低的日偏食。
