We present experimental evidence of the coronal mass ejection ( CME ) breakout reconnection , observed by the TESIS EUV telescope .
The telescope could observe solar corona up to 2 R _ { \odot } from the Sun center in the Fe 171 Å line .
Starting from 2009 April 8 TESIS , observed an active region ( AR ) that had a quadrupolar structure with an X-point 0.5 R _ { \odot } above photosphere .
A reconstructed from the MDI data magnetic field also has a multipolar structure with an X-point above the AR .
At 21:45 UT on April 9 , the loops near the X-point started to move away from each other with a velocity of \approx 7 km s ^ { -1 } .
At 01:15 UT on April 10 , a bright stripe appeared between the loops , and the flux in the GOES 0.5–4 Å 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 15:10 UT , the CME started to accelerate impulsively , while at the same time a flare arcade formed below the CME .
After 15:50 UT , the CME moved with constant velocity .
The CME evolution precisely followed the breakout model scenario .
