A partial lunar eclipse will occur in Hong Kong in the small hours of October 29 (Sunday). The elevation of the moon will be rather low during the eclipse. If weather permits, the event can be directly observed with unaided eyes at places with an unobstructed view to the west.
 
     The lunar eclipse will begin at 1.59am on that day, with the maximum eclipse occurring at 4.14am. This partial lunar eclipse only has an umbral magnitude of around 0.13, meaning that about 13 per cent of the moon's diameter will enter the umbra (total shadow) of the earth at the maximum eclipse. Details of this partial lunar eclipse are as follows:
 

Date	Time	Phenomenon	Elevation	Direction (Azimuth)
October 28 (Saturday)	5.25pm	Moonrise	-1 degree	East-northeast (78 degrees)

	4.54am	Moon exits umbra	21 degrees	West (277 degrees)

     In the small hours on October 29, members of the public can watch the whole event via a webcast to be jointly hosted 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 Creative Education Unit of the Hong Kong Federation of Youth Groups.
