AB: We for the first time use simultaneously observed EUV images to reconstruct the 3D shape of magnetic loops which emerge from an active region. The images were taken by the two EUVI cameras of the SECCHI telescopes onboard the STEREO spacecraft. At the time the data was taken, the heliocentric separation of the two STEREO probes was 12 degrees. We show that under these conditions it is possible to obtain a reliable three- dimensional reconstruction of suciently bright loops as they usually emerge from an active region. The result is compared with field lines derived from a coronal magnetic field model extrapolated from a surface magnetogram. The magnetogram was abserved by SOHO/MDI only 9 seconds before the the EUV images were taken.
