Correo Argentino S.A., the official postal service of Argentina, has issued a postage stamp in its collection "Cosmos and Science" to honor the Pierre Auger Observatory. The stamp, valued at 0.75 pesos, depicts a Cherenkov radiation detector, part of the surface array of the Observatory, installed in the departments of Malargüe and San Rafael, Mendoza. Also depicted in the stamp is a fluorescence detector building, an expression for the energy of the ultra-high energy cosmic rays, and the logo of the Observatory.

The stamp has been issued in edition of 100,000 copies. The design is by MOSCA80, for the Correo Oficial de la República Argentina S.A. Philatelic Department. The stamp measures 34 x 44 mm, is issued in sheets of 20, and is printed in four colors plus metallized ink on paper without watermark or phosphorescence. 3,000 first day covers were issued.

Pierre Auger Observatory shares cosmic-ray data with public, students (3 July 2007)

The Pierre Auger Collaboration has begun the public release of one percent of the cosmic-ray events recorded by the Observatory in Argentina. New cosmic-ray data—about 70 events per day—will be posted on a daily basis.

The one-percent release is part of the worldwide Pierre Auger education and outreach program. It will allow teachers to expose students to real scientific data and the breathtaking processes that take place in the cosmos, hurling charged particles toward Earth. Data are provided both as graphical displays and in tabular form. For each cosmic-ray air shower, the Web sites show the energy and direction of the incoming cosmic-ray particle. The public data provides information on cosmic-rays with extremely high energy, up to 5 x 1019 electron volts (eV).

The data and their visualizations are available by clicking on the Event Display link in the Navigation Bar on the right, or by going to http://www.auger.org.ar.

The full text of the Press Release is found at interactions.org.


75% of Surface Detectors are Operational (11 May 2007)

Another construction milestone has been passed. As of 11 May three quarters of the surface array (1200 detector stations) are now in operation! There are 1689 tanks deployed or in the pipeline. We expect the last of the tanks to be at the Observatory ready for assembly by August. There are nearly 200 electronics kits ready for installation and the rest are expected to be ready in another two months.

All of the fluorescence telescopes are operational. A complete calibration is underway and should be complete by September.

Auger will once again be a major participant in the International Cosmic Ray Conference with 35 talks and posters. The conference this year will be held in Mérida, Mexico.
