Abstract (from CDS):

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 8.15h and 12.54d: we find upper limits of 0.10mag and 0.09mag, respectively.
