Llano de Chajnantor Observatory is the name for a group of astronomical observatories located at an altitude of over 4,800 m (15,700 ft) in the Atacama Desert of northern Chile. The site is in the Antofagasta Region approximately 50 kilometres (31 mi) east of the town of San Pedro de Atacama .
The Atacama Pathfinder Experiment (APEX) is a radio telescope 5,064 meters above sea level, at the Llano de Chajnantor Observatory in the Atacama Desert in northern Chile, 50 km east of San Pedro de Atacama built and operated by three European research institutes.
The ASTE was deployed to its site on Pampa La Bola, near Cerro Chajnantor and the Llano de Chajnantor Observatory in northern Chile. [1] The antenna shows excellent performance including a surface accuracy of 19 μm (0.00075 in) r.m.s. [2] The telescope is remotely controllable from multiple sites through satellite connections and the Internet.
The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau – near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment. This location was chosen for its high elevation and low humidity, factors which are crucial to reduce noise and decrease signal attenuation due to Earth's atmosphere. [1]

The Quadrantid meteor shower is one of the strongest, and quickest, meteor showers of the year. Here’s what you need to know to observe it during peak activity.
The site is located less than 5 km (3.1 mi) north-northeast of the Llano de Chajnantor Observatory, where the Atacama Large Millimeter Array (ALMA) is located, but is over 580 m (1,900 ft) higher in elevation.
