Scaler mode of the Auger Observatory and Sunspots
Recent data from the Auger Observatory on low energy secondary cosmic ray
particles are analyzed to study temporal correlations together with data on the
daily sunspot numbers and neutron monitor data. Standard spectral analysis
demonstrates that the available data shows 1/f^{\beta} fluctuations with
{\beta} approximately 1 in the low frequency range. All data behave like
Brownian fluctuations in the high frequency range. The existence of long-range
correlations in the data was confirmed by detrended fluctuation analysis. The
real data confirmed the correlation between the scaling exponent of the
detrended analysis and the exponent of the spectral analysis.Comment: 20 pages, 6 figures, to be published in Astrophysical Journal
