Abstract: We present new UBVRI observations of the magnetic Bp star σ Ori E. The basic features of the star's lightcurve have not changed since the previous monitoring by Hesser et al. (1977), indicating that the star's magnetosphere has remained stable over the past three decades. Interestingly, we find a rotation period that is slightly longer than in the Hesser et al. (1977) analysis, suggesting possible spindown of the star.
