Context. There are more than 3000 confirmed and probably known Galactic planetary nebulae (PNe), but central star spectroscopic information is available for only 13% of them.
Aims. We have undertaken a spectroscopic survey of the central stars in PNe to identify their spectral types.
Methods. We performed spectroscopic observations at low resolution with the 2-m telescope at CASLEO, Argentina.
Results. We present the spectra of 46 central stars of PNe, most of them are OB-type and emission-line stars.
Key words: surveys / planetary nebulae: general / Atlases / stars: Wolf-Rayet
Based on data collected at the Complejo Astronómico El Leoncito (CASLEO), which is operated under agreement between the Consejo Nacional de Investigaciones Científicas y Técnicas de la República Argentina y Universidades Nacionales de La Plata, Córdoba y San Juan, Argentina.
The reduced spectra (FITS files) are available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/531/A172
