             abstract = "The Solar TErrestrial RElations Observatory - STEREO was launched 
                         on October 25th, 2006 and is composed of two nearly identical 
                         spacecrafts, one ahead of Earth in its orbit, the other trailing 
                         behind - to provide the »rst- ever stereoscopic measurements to 
                         study the Sun and the nature of its coronal mass ejections, or 
                         CMEs. Each spacecraft has, among others, an instrument package 
                         called Sun Earth Connection Coronal and Heliospheric Investigation 
                         (SECCHI), which is composed by 4 sets of instruments: SECCHI EUVI: 
                         Extreme UltraViolet Imager; SECCHI COR1: Inner Coronagraph; SECCHI 
                         COR2: Outer Coronagraph; SECCHI HI: Heliospheric Imager. These 
                         instruments will study the evolution of CME's from birth at the 
                         Sun's surface through the corona and interplanetary medium to its 
                         eventual impact at Earth. Since 1996, the Large Angle and 
                         Spectrometric Coronagraph (LASCO), aborde the Solar and 
                         Heliospheric Observatory (SOHO), is able to observe the solar 
                         corona from 1.1 to 32 solar radii (LASCO C1, C2 and C3 »eld of 
                         view). This observation capability has improved substantialy since 
                         STEREO SECCHI package is able to observe from 1.4 solar radii up 
                         to 1 AU (earth orbit). In this work, we show some preliminary 
                         observations and measurements of CMEs from 1.4 to beyond 32 solar 
                         radii, usind observations from the SECCHI package. Since the SOHO 
                         is still in operation, we can perform combined measurements from 
                         both SECCHI and LASCO for a few CMEs occurred since STEREO started 
                         its observations.",
