Light curves (magnitude vs. time) of candidate lm0073m17729 in the EROS blue passband (upper panel), and the EROS red passband (lower panel). The black solid lines show the best no-blend microlensing fit. No data is available in the MACHO catalog. The hints of variability outside the main bump and the asymmetry, especially visible in the change of the blue baseline after the maximum, make it unlikely that this event is a geniune microlensing event.
