Abstract
OGLE I-band observations for [M2002] SMC 20671, the optical counterpart of SXP 4.78, were searched for periodicities with P > 0.5 days. Three sets of photometric signals were detected, which are attributed to non-radial pulsations of the Be star. All signals show considerable variability in power over the 16 seasons studied. The most likely periods of the NRPs are 0.5826, 0.6164, and 0.6424 days.
