Description
Observations of the Local Arm have been carried out in the near-infrared
with the 1.5 m ``Carlos Sanchez'' telescope in Tenerife. A model of the
disc with adjustable parameters fitted to reproduce the DIRBE-COBE
survey, has been subtracted from the observational data in order to
obtain a clean map of the Local Arm, uncontaminated by other components
of the disc. The arm is more than 70 pc over the plane and is wider than
200 pc. At a latitude of about 80(deg) the deviation of the arm from the
galactic plane is so large that was only partially observed with our
observational window of triangle b =3D +/- 6(deg) . The elevation over
the plane vanishes and the width decreases as the Arm comes closer to
the Sun.
