The Department of Terrestrial Magnetism (DTM) of the Carnegie Institution of Washington (CIW) decided to establish a magnetic observatory in Peru in 1917. John A. Fleming, who belonged to the DTM, led the search for an ...

This article reviews the scope of several Observatories found by a search in the Internet through the Google search engine. After examining these observatories, it describes the aims and initial accomplishments of the ...

The present paper will make a brief description of the four radars available at the Observatory. We have included in the bibliography a list of references where more detailed descriptions of these systems can be found. The ...

Early earthquake warning is a rapidly developing capability that has significant ramifications for many fields, including astronomical observatories. In this work, we describe the susceptibility of astronomical facilities ...

We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud identifications resulting ...

The Pierre Auger Observatory is designed to study cosmic rays with energies greater than View the MathML source. Two sites are envisaged for the observatory, one in each hemisphere, for complete sky coverage. The southern ...

The purpose of these historical notes is to present the early history of the Jicamarca Radio Observatory (JRO), a research facility that has been conducting observations and studies of the equatorial ionosphere for more ...

We present the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 1017 eV with the surface detector array of the Pierre Auger Observatory, reporting on both the phase and the amplitude ...
