The next partial lunar eclipse visible in Hong Kong will take place on 7 July 2028 (Friday). The partial lunar eclipse will begin at 1:08 am and reach the maximum eclipse at 2:20 am. The partial eclipse will end at 3:31 am when the Moon exits the umbra completely. During the partial lunar eclipse, the Moon's altitude will range between 26 degrees and 42 degrees. It is possible to observe the eclipse from any district in Hong Kong as long as the view is unobstructed by buildings. Interested observers are advised to choose a location with a wide view to the south and southwest, such as waterfront promenades or parks in various districts.

When the Sun, the Earth and the Moon are aligned, the Moon will enter the Earth's shadow, resulting in a lunar eclipse. Depending on how the Moon comes in contact with the Earth's shadow, lunar eclipses can be divided into three types, namely the penumbral eclipse, partial eclipse and total eclipse. A penumbral lunar eclipse happens when the Moon enters the penumbra of the Earth; whereas a partial lunar eclipse happens when only part of the Moon enters the Earth's umbra. When the Moon enter the Earth's umbra completely, a total lunar eclipse results.

These two images were taken during the phase of the penumbral lunar eclipse before the partial lunar eclipse on 7 August, 2017. The image on the left was taken 1 hour before the partial eclipse. The image on the right was taken 10 minutes before the partial eclipse. The penumbral lunar eclipse is not obvious at its early stage. When the partial eclipse approaches, it can be seen easily that the surface of the Moon is dimmer.
