Lulin Observatory (Chinese: 鹿林天文台; pinyin: Lùlín Tiānwéntái; literally: "Deer Forest Astronomical Observatory") is an astronomical observatory operated by the Institute of Astronomy, National Central University in Taiwan.

It is located at the summit of Mount Lulin, on the border of Chiayi County and Nantou County, near Yushan National Park. In 2007, Comet Lulin (C/2007 N3), which will come nearest the Earth on 24 February 2009, was found by this observatory.

The Lulin 1 meter had its first light in September 2002, after 10 years of development.[1]


  • LOT Cassegrain telescope (D=1-m, f/8)
  • SLT R-C telescope (D=0.40-m, f/8.8) by RC Optical Systems [2] or 76-cm Super Light Telescope (SLT)
  • Four TAOS robotic telescopes (D=0.50-m, f/1.9)


Lulin Sky Survey (LUSS)[edit]

The Lulin Sky Survey searched for Near-Earth objects from 2006 to 2009.[3] The Lulin Sky Survey Telescope,[4] a 16-inch (41 cm) Ritchey–Chrétien telescope with a field of view of 27 arcminutes, was operated remotely from mainland China, with robotic software developed in-house.[5][6] In addition to searching for new objects, the survey refined the orbits of known minor planets and comets, and performed photometric analysis of a subset of objects.[6] The principal investigator, student Quan-Zhi Ye of Sun Yat-sen University, was awarded the 2007 Shoemaker NEO Grant to develop the project.[3] Ye later identified a comet from images collected in July 2007 by collaborator Chi Sheng Lin; the unusual retrograde comet, formally named C/2007 N3, became known as Comet Lulin. It made its closest approach to Earth in February 2009.[7] Over the course of the survey, 781 new objects were discovered, including Comet Lulin and three fragments of commet 73P/Schwassmann-Wachmann.[6] The LUSS project benefited from its location at a longitude with few other observatories looking for minor planets.[6]
