Cerro Armazones

Cerro Armazones is a mountain located in the Sierra Vicuña Mackenna of the Chilean Coast Range, approximately 130 km (81 mi) south-east of Antofagasta in the Antofagasta Region, Chile. Before construction started on the European Extremely Large Telescope, the summit was a horizontal control point with an elevation of 3,064 metres (10,052 ft).[1] The new elevation is 3,046 m (9,993 ft).[2] It is located in a privileged zone for optical astronomy because it has 89% cloudless nights a year.[3] It currently hosts the 1.5 m (5 ft) Hexapod-Telescope and other telescopes at the Cerro Armazones Observatory.

On 26 April 2010, the European Southern Observatory Council selected Cerro Armazones as the site for the planned Extremely Large Telescope, and construction began in June 2014.[4][5]

gollark: What do you mean? Should you not have planned this before?
gollark: Take SIM cards. Why are they still discrete hardware devices, *running Java*?
gollark: To be honest the phone network and everything associated with it seems terribly designed.
gollark: And there probably will be, since they can hardly vet all of them thoroughly: there are probably a lot of VoIP providers.
gollark: But they *can*, if some provider comes along which is willing to verify a call with a faked number.
