Resumen:
Since data-taking began in January 2004, the Pierre Auger Observatory
has been recording the count rates of low energy secondary cosmic ray
particles for the self-calibration of the ground detectors of its
surface detector array. After correcting for atmospheric effects,
modulations of galactic cosmic rays due to solar activity and transient
events are observed. Temporal variations related with the activity of
the heliosphere can be determined with high accuracy due to the high
total count rates. In this study, the available data are presented
together with an analysis focused on the observation of Forbush
decreases, where a strong correlation with neutron monitor data is
found.
