Magnetic clouds (MCs) are closed magnetic structures embedded in interplanetary coronal mass ejections (ICMEs). They have physical interest by their own, and, more recently, by their Earth magnetosphere effects.

Data from the period 2008-2014 Stereo A and B (MAG, PLASTIC and SWEA PAD sensors) and from different ICME catalogues have been used to elaborate an exhaustive list of MCs.

To establish the boundaries of those  MCs we have used six criteria, like a low-beta plasma or higher magnetic field intensity than the values in calm solar wind conditions.

In this presentation we show the orientation of the axis (latitude and longitude) of all MCs in that period of time as determined by the well-known Hidalgo model for their magnetic topology.
