List of observatory codes

Jump to: navigation, search

This is a list of observatory codes, or IAU codes, with their corresponding astronomical observatories.[1] The Minor Planet Center (MPC) – a service of the International Astronomical Union – assigns for each registered observatory a 3-digit code.

The code serves as a unique identifier for observations taken of hundreds of thousands of minor planets and thousands of comets orbiting in the Solar System. More than 150 millions such astrometric records exist.[2] This list is based on MPC's periodically published and revised "List Of Observatory Codes". Over time, the number of astronomical observatories worldwide has been growing constantly. As of May 2016, MPC's official list contains a total of 1972 observatories.[1]

The registry is limited to observatories which perform minor planet observations. While this includes most optical telescopes of note and a great many amateur facilities, it does not include the U.S. National Solar Observatory or many notable radio observatories (such as the Llano de Chajnantor Observatory, MeerKAT, or the South Pole Telescope).

The following list contains an observatory's name and code as used by the MPC, its location and, optionally, a link to the corresponding article on Wikipedia and an external link to the observatory webpage.[1]
