Abstract—We
obtained 448 magnitude estimates for the star BM Ori in each of
the UBVRI bands. Observations with apertures of various
diameters are used to allow for the background. Reduction of the
observations to the standard UBVRI system is described.
The light curves are presented. We failed to confirm the
existence of a secondary minimum. The observational errors are
analyzed.
