Scientists celebrate Inauguration
of the Pierre Auger Observatory
A selection of articles from around the world (9-NOV-2007):
Argentina issues postage stamp to honor the Pierre Auger Observatory (14 July 2007)
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.
Shown here is the day-of-issue postmark, which depicts a Cherenkov tank. (Click image for larger picture.)
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
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
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

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.
