Recent data from the Auger Observatory on low energy secondary cosmic ray particles are analyzed to study temporal correlationstogether 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 approx 1in 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 Hurst exponent of the detrended analysis and the exponent of the spectral analysis.
