ResumoA statistical study of the correlation scale on structures around Venus was developed using magnetic field and electron density data obtained from the Magnetometer and the Analyzer of Space Plasmas and Energetic Atoms (ASPERA-4) instruments (respectively), on board of the mission Venus Express (VEX). The correlation scales have been calculated by the correlation length, which is a characteristic length over which fluctuations in a variable are correlated. We limited the study to the frequency range 8 to 50 mHz because previous studies have shown that ULF (Ultra Low Frequency) waves produced in the foreshock have highest power in this range. Frequencies below 8mHz were filtered out using the Fourier transform. In this study the correlation length was calculated by an exponential fit employed to the autocorrelation curve. The auto-correlation function was calculated lagged by a time between 0 and 60 seconds and sliding a window of 120s width across the data. We also converted the obtained correlation length from temporal to spatial scale by multiplying by the solar wind velocity. Here, the ASPERA-4/IMA (Ions Mass Analyzer) velocity was used. In order to find the size of the structure in different regions of the Venus magnetosphere, statistical maps showing the median correlation length in spatial bins around Venus have been produced covering the all data from the VEX mission (May 2006 to September 2014).
