The first results of spatially resolved spectroscopic observations of the disk around β Pictoris are presented. These observations were performed with UVES at the 8 m VLT at ESO, Chile, during several runs in 2001/2002. Seeing conditions were always ⪉0.6 arcsec\ and the slit had a length of 8 arcsec to 12 arcsec in individual observations. The observed spectral range is 0.3 μm to 1 μm, and the spectral resolution R˜ 90,000. The highlights of these observations include (1) the large number of detected disk lines, (2) the large radial extent of the disk gas (to the limit of our observations) and (3) the large scale height of the disk gas at large distances from the star (i.e. the degree of flaring).
