Global Observatory Network

Gathering at our upcoming ICCP9 and Yale-NUS meetings in January are representatives and directors of many of the leading observatories in Asia, and this site provides links to the observatories as well as an explorable Google Earth map showing the observatories and their locations from space.


India has two main optical observatories, both administered from the Indian Institute of Astrophysics (IIA) in Bangalore

The Vainu Bappu Observatory

The Vainu Bappu Observatory is outside of Vellore India, in a very dark site and includes a 2.3-meter telescope and two 1.0 meter telescopes. The 2.3-meter telescope is equipped with an echelle spectrograph and is used for high resolution work on stars.

Indian Astronomical Observatory, Hanle


The Hanle observatory features a 2.0 meter telescope in a high-altitude site near the Himalayas 4500 meters above sea level. A small 0.5-meter remotely operated telescope is also on site, in a collaboration with Washington University, St. Louis, USA, for observing photometric variations in AGN.

South Korea

South Korea has two main observatories for optical work, described below. Both are administered from the Korea Astronomy and Space Institute (KASI).

The Sobaeksan Optical Astronomy Observatory (SOAO)

The Sobaeksan Optical Astronomy Observatory ( SOAO ) is an observatory in Tanyang in Sobaek Mountains. It was opened in 1978 and is equipped with a 61- cm reflecting telescope.

The Bohyunsan Optical Astronomy Observatory (BOAO) Bohyunsan Optical Astronomy Observatory ( BOAO ) is an observatory on the mountain Bohyun in Youngchun. It was founded in 1996 and has a Ritchey -Chrétien telescope with 1.8 meter in diameter.


The Langkawi National Observatory

Located in beautiful Langkawi Island, in Northern Malaysia. Features a 0.5-meter telescope, a well-equipped visitor center, and a suite of solar telescopes that include CaIIK, H-alpha and white light imaging.


The Lulin Observatory


At the summit of Mount Lulin at 2400 meters altitude, the Lulin Observatory includes a 1-meter telescopes, a 0.4-meter R-C telescope, and four TAOS robotic telescopes, with a 0.5-meter aperture.


The Thai National Observatory (TNO)


Located at 2,457 meters above sea level near Chiang Mai, the Thai Observatory has a 2.4-meter reflecting telescope and a 0.5-meter telescope. The drive system of the 2.4-meter telescope has been enabled to have automatic control of the dome structure. The telescope is manufactured at EOST in Tucson, Arizona, USA. The 2.4 m diameter primary mirror has been fabricated and undergone fine polishing at LZOS facility in Russia.
