Abstract: We present the results of a spectroscopic monitoring program of the binary system Delta Scorpii, whose primary became a Be star after the last periastron encounter in the Summer of 2000. The observations cover a period of 2 years (March 2001–June 2003) and are a continuation of our previous campaign reported in Miroshnichenko et al. (2001). We found that the emission-line spectrum was gradually strengthening over the whole monitoring period.
