Latitude, longitude and altitude of Ckoirama Observatory; where can things like this be looked-up? This answer to Is Starlink 1130 (Darksat) really dimmer? links to the March 16, 2020 paper in arXiv First observations and magnitude measurement of SpaceX's Darksat which finds only a modest decrease in brightness:


  Results. The calibration, image processing and analysis of the Darksat Sloan g’ image gives an estimated Sloan g’ magnitude of 7.57±0.04 at a range of 976.50 km. For STARLINK-1113 an estimated Sloan g’ magnitude of 6.69±0.05 at a range of 941.62 km was found. When scaled to a range of 550 km, a reduction of (55 % ± 4.8 %) is seen in the reflected solar flux between Darksat and STARLINK-1113.


The v1 preprint says 


  ...using the longitude(24.1° west) and latitude (69.9°south) of the Ckoirama observatory...


which puts the Ckoirama observatory under about 4500 meters of freezing antarctic water (first image).

If I invert the latitude and longitude assignments it returns to the Atacama desert where it belongs. If I instead type "Ckoirama observatory" in maps.google.com I get a pin on a map near 24.0894 S, 69.9305 W but the satellite image only shows a hole in the ground. (second image)

That link leads to http://www.astro.uantof.cl/research/observatorios/ckoirama-observatory/ which is very informative but has no latitude, longitude or altitude information. 5 Awesome Observatories Around The World mentions that Ckoirama is;


  the first observatory built by Chilean engineers


and links to Astrotourism in Chile but no specific information.

Question: What are the latitude, longitude and altitude of Ckoirama observatory? Is there a central location where coordinates like these can be looked up?
Near the pinned location, at 24.0893&deg;S 69.9306&deg;W,
Bing Maps shows a building like the one in the University of Antofagasta photos,  with signs of recent construction.



It's probably a matter of time until Google updates their satellite imagery in that region.

The Minor Planet Center maintains a list of observatory codes with positional information.
A related page there says:


  The KML file of observatory-code locations has been removed, following a request from some Spanish observers concerned about security at remote, unattended sites.
