  • Partial solar eclipse in Hong Kong on March 9

  • Friday, 26th February 2016

A total solar eclipse will occur on 9 March (Wednesday), but it will be visible only as a partial solar eclipse in Hong Kong, weather permitting.

It will begin at 8:05 a.m. and end at 9:57 a.m., with the maximum eclipse occurring at 8:58 a.m. This partial solar eclipse has a magnitude of 0.331, meaning that 33.1% of the Sun's diameter will be obscured by the Moon at maximum eclipse. Please refer to the attached diagram for the path of the Sun and the Moon during this partial solar eclipse.

Details of the partial solar eclipse are as follows:

Hong Kong Time Direction (Azimuth) Elevation

Eclipse begins

8:05 a.m. East-southeast (103 degrees) 19 degrees

Maximum eclipse

8:58 a.m. East-southeast (110 degrees) 31 degrees

Eclipse ends

9:57 a.m. East-southeast (120 degrees) 43 degrees

As the elevation of the Sun is rather high during the eclipse, most places with an unobstructed view to the east-southeast are suitable for viewing the event.

Members of the public should never look directly at the Sun with naked eyes nor through a telescope in order to avoid severe damages to their eyes. 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 (the Observatory):
