We present the results of measurements on astronomical site characterisa- tion in the north-west of Argentina in the period May 2008 to July 2009. The Macón site was originaly selected for testing the posibility of a large astronomical facility by the European Southern Observatory (ESO). Initial measurements were performed at the west edge of de the mountain (ESO site) but later, the location of the site was changed 400 m to the north-east (U-Site) because in the original place the shape of the mountain induced an aceleration of the wind. The winds in the U-Site are significantly reduced while seeing remains in the same range of values.
