PAMPA   AMARILLA  IN  ARGENTINA : CONSTRUCTION  SITE  OF  THE SOUTHERN  PIERRE  AUGER  OBSERVATORY  

Satellite picture of town of Malarüe (Mendoza province) with surroundings, with the site of Pierre Auger Observatory marked by red line. On the left the Andes mountain range is visible.

Construction of a power line to Los Leones hill, on which prototype fluorescence detector are located.

View from the Coihueco hill - proposed location of the next "eye" of the fluorescence detector.

Typical vegetation of the Pampa . The name Pampa Amarilla (i.e. Yellow Pampa) comes from the vest areas covered with yellow grass.

A beautiful photograph of the Los Leones Building (under construction) and the communications antenna with the Southern night sky at the background. The picture was taken by Andres Risi and Mario Santarrosa during the recent sky background measurements at Malargue. 
The two bright stars (on the right) are Alfa and Beta Centauro. Below them and on the right of the antenna is the Southern
Cross and on the left of the antenna and partially screening by it is the Great Magallegan Cloud. 

Exposure time: about 1 hour.

newly assembled detectors wait for the morning shift of the deployment crew.

only in the office building the lights are on due to a data acquisition shift.
