  The Be star \delta\ Scorpii is an interesting binary system, whose primary
companion created a circumstellar disk after the periastron passage of the
secondary in 2000, being since then classified as Be. This work presents the
results of a long-term monitoring of this star in broad-band imaging
polarimetry. The observational data collected since 2006 in the Pico dos Dias
Observatory (Brazil) show a variable polarization that seems to correlate with
the photometric light curve. From this data we see that the disk density varied
since 2006; furthermore, the data suggests that there was some disturbance of
the disk during the last periastron passage in July, 2011.
