An annular solar eclipse will occur on December 26 (Thursday), but it will be visible as a partial solar eclipse in Hong Kong. As the elevation of the sun will be rather high during the eclipse, the event can be best observed at places with an unobstructed view towards the south to southwest if weather permits.
The eclipse will begin at 12.17pm and end at 3.22pm, with the maximum eclipse occurring at 1.55pm. This partial solar eclipse will have a magnitude of 0.46, meaning that 46 per cent of the sun's diameter will be obscured by the moon at maximum eclipse. The path of the sun and the moon during this partial solar eclipse is indicated in the Annex.
Details of the partial solar eclipse are set out in the following table:
| Time | Phenomenon | Elevation | Direction (Azimuth) |
| 12.17pm | Eclipse begins | 44 degrees | South (178 degrees) |
| 1.55pm | Maximum eclipse | 39 degrees | South-southwest (207 degrees) |
| 3.22pm | Eclipse ends | 27 degrees | Southwest (226 degrees) |
Members of the public should never look directly at the sun with the naked eye nor through a telescope to avoid severe eye damage. A safer method is to project the sun's image through a pinhole or a telescope onto a piece of white paper or cardboard and view the projected image. An illustration of the method is given on the website of the Hong Kong Observatory at www.hko.gov.hk/en/gts/event/event-solar-eclps16.htm.
Members of the public can watch the whole event via a webcast to be jointly provided by the Hong Kong Observatory, the Hong Kong Space Museum, the Ho Koon Nature Education cum Astronomical Centre (sponsored by Sik Sik Yuen), Po Leung Kuk Ngan Po Ling College and the Hong Kong Sheng Kung Hui Solar Tower‧Camp on the following webpage: www.hko.gov.hk/en/gts/event/webcast-20191226.htm.
