It is shown that the data on low-energy cosmic rays collected at the Oulu (Northern Finland) neutron monitor after the full-halo coronal mass ejection of July 14, 2000 exhibit well-defined extended self-similarity (ESS) in the time increments interval 0.3–17 hours. Comparison of the energy and ESS spectra of the cosmic-ray intensity fluctuations with those of the solar wind supports the idea of the solar-wind origin of these fluctuations.
