Penumbral lunar eclipse in Hong Kong on November 30
***************************************************
     This year's third penumbral lunar eclipse will occur in Hong Kong on the evening of November 30 (Monday). A penumbral lunar eclipse occurs when the Moon only enters the penumbra of the Earth but not the umbra. During the event, the Moon will become slightly dimmer. A special feature of the coming lunar eclipse is that the eclipse will begin before moonrise.
      
     As the elevation of the Moon will be rather low during the eclipse, the event can be best observed at places with an unobstructed view of the horizon towards the east and northeast. Details of this penumbral lunar eclipse are as follows:
      
Date Time Phenomenon Elevation Direction (Azimuth)
November 30 (Monday) 3.30pm Moon enters penumbra Below the horizon --
5.38pm Moonrise -1 degree East-northeast
     (68 degrees)
5.42pm Maximum eclipse 0 degree East-northeast
     (68 degrees)
7.56pm Moon leaves penumbra 29 degrees East-northeast
     (78 degrees)
       
     The eclipse will begin at 3.30pm and end at 7.56pm, with the maximum eclipse occurring at 5.42pm, which will be four minutes after moonrise. The whole process (from moonrise to the moon leaving the penumbra) will last for two hours and 18 minutes.
      
     For the latest weather conditions and the astronomical observation conditions on November 30, please refer to the 9-day Weather Forecast issued by the Hong Kong Observatory (www.hko.gov.hk/en/wxinfo/currwx/fnd.htm) and the Weather Information for Astronomical Observation webpage (www.hko.gov.hk/en/gts/astronomy/astro_portal.html).
      
     The next lunar eclipse observable in Hong Kong will be a total lunar eclipse on May 26, 2021.
