%3 Minimum variance analysis of interplanetary.pdf
%@dissemination WEBSCI; PORTALCAPES.
%X The minimum variance analysis of interplanetary coronal mass ejections (ICMEs) observed close to the Earth's orbit around solar cycle 23 maximum (1998-2002) was performed. The ICMEs were classified in three categories: magnetic clouds (MC), undefined ejecta (UE), and complex ejecta (CE). An analysis of the full ICMEs set shows that the average of minimum variance direction inclination angle is 1.6 degrees +/- 24.8 degrees in relation to the ecliptic plane, with more than 33% of the events presenting inclination angles lower than 10 degrees. The average of minimum variance direction azimuthal angle (in relation to the Sun-Earth line) was 56 degrees. However, around 60% of the ICMEs presented an azimuthal angle lower than 30 degrees, close to the radial direction. It was also observed that the MC set had lower axial (intermediate variance) inclinations relative to the ecliptic plane than the UE and CE events. The intermediate variance axis is close to 90 degrees to the Sun-Earth line. The results obtained in the present analysis were also compared with previous works, permitting a comparison of the ICMEs orientations in solar cycle 23 with previous sor cycles.
