Transient luminous events observed by a pinhole camera

Abstract:

The next generation of experiments devoted to study extreme energy cosmic rays will be at space platforms. Recent experiments have shown that the UV light background is more complex than previous models. Therefore, the observation of transient luminous events(TLE) at the upper atmosphere will be important. Information about the time and space evolution of this very fast events may need to be recorded, this impose requirements of a wide field of view and the largest focus depth. The simplest optical design: a pinhole camera fulfils this characteristics. This pinhole camera have a multianode photomultiplier (64 pixels) that allow us to register 2-d images of TLEs. In this work we present the observations of some events recorded from Sierra Negra Volcano in Mexico and its capabilities in order to use it as a monitoring device.
