  We present photometric observations of the MACHO-SMC-1 microlensing candidate
collected by the OGLE-2 project. We show light curves of both components of the
1.6 arcsec blend: microlensed star and its optical companion. We find the
contribution of the optical companion to the total flux to be 24% and confirm
presence of the small amplitude periodic oscillations in the light curve of the
lensed star with the period of 5.096 days and amplitude 0.05 mag. The lensed
star is probably an ellipsoidal binary system.
