Abstract
We present a FORS1 (VLT) spectroscopic study of the stellar population content in PKS 2005-489, one of the nearest BL Lac objects, with a redshift of 0.071 (Falomo et al 1987). Low dispersion long slit spectroscopy, covering the interval between 484 nm and 720 nm, was obtained with a total integration time of 2400 seconds. The data reduction was done in the common manner using IRAF tasks for long slit spectra.
