Spectral indices and flatness scaling exponents corresponding to solar wind plasma measurements before, during and after a coronal mass ejection (CME) detected by NASA's Wind spacecraft on September 2014 have been obtained. The Politano-Pouquet (PP) law for isotropic and incompressible magnetohydrodynamic (MHD) turbulence has been validated over a series of selected time intervals. The performed analysis showed that turbulence was well established within most of such intervals and several mean energy transfer rates were computed. Furthermore, the results detailed in this essay suggest possible correlations between the aforementioned energy transfer rates and the spectral indices and flatness scaling exponents, and also between enhanced intermittencies and large values of the mean energy transfer rates.
