Abstract (from CDS):

We report on the analysis of eight years of Massive Compact Halo Objects (MACHO) data for the source RX J0520.5-6932. A regular period of 24.4 d has been confirmed; however, this is manifest almost entirely in the red part of the spectrum. A major outburst, lasting approximately 200 d, was observed, which increased the apparent brightness of the object by approximately 0.15 mag without significantly altering its V -R colour index. This outburst was also seen in X-ray data. The evidence from this analysis points to the identification of this object as a Be/X-ray binary with a periodically variable circumstellar disc and a very early optical counterpart.
