The non-negligible effect of magnetic holes on the magnitude-of-B magnetic power spectral density of the fast Alfvenic coronal-hole-origin solar wind at 1 AU
Abstract
To estimate the effects of magnetic holes on the magnitude of B magnetic power spectral density, a 2-day interval of fast coronal-hole-origin plasma at 1 AU is examined. The magnetic holes are identified and removed from the magnetic time series, and the power spectral density of the hole-free time series is compared with the power spectral density of the original time series. The magnetic holes were found to contribute about a factor of two to the amplitude of the power spectral density.
