Abstract

Recording tracks of stars traversing the field of view of the Auger's fluorescence detector (FD) is a powerful tool to monitor various FD parameters. Regular control of these tracks would allow checking the telescope's stability during the whole life of the experiment, estimated to be about 20 years. The prototypes used during the engineering array phase have been equipped with a novel optoelectronic system that measured the DC anode current. Dim stars were clearly recorded. We report the results of a reconstruction performed to determine the pointing of a telescope as well as comparisons of a PMT's response to shower and star signals.
