We present experimental evidence of the coronal mass ejection (CME) breakoutreconnection, observed by the TESIS EUV telescope. The telescope could observesolar corona up to 2 $R_\odot$ from the Sun center in the Fe 171 \AA\ line.Starting from 2009 April 8 TESIS, observed an active region (AR) that had aquadrupolar structure with an X-point 0.5 $R_\odot$ above photosphere. Areconstructed from the MDI data magnetic field also has a multipolar structurewith an X-point above the AR. At 21:45 UT on April 9, the loops near theX-point started to move away from each other with a velocity of $\approx$ 7 kms$^{-1}$. At 01:15 UT on April 10, a bright stripe appeared between the loops,and the flux in the GOES 0.5-4 \AA\ channel increased. We interpret the loops'sideways motion and the bright stripe as evidence of the breakout reconnection.At 01:45 UT, the loops below the X-point started to slowly move up. At 15:10UT, the CME started to accelerate impulsively, while at the same time a flarearcade formed below the CME. After 15:50 UT, the CME moved with constantvelocity. The CME evolution precisely followed the breakout model scenario.
