Using the exceptional long‐term monitoring capabilities of the MACHO project, we present here the optical history of LMC X‐2 for a continuous 6‐yr period. These data were used to investigate the previously claimed periodicities for this source of 8.15 h and 12.54 d: we find upper limits of 0.10 mag and 0.09 mag, respectively.
