Following an alert by the MACHO group, the PLANET collaboration has made detailed follow-up observations of the microlensing event in the SMC, MACHO 98-SMC-l. The lens is a binary and in consequence it is possible to obtain the relative source-lens proper motion as the source crosses a caustic. Two acceptable models have been found to describe the source-lens configuration, both of which suggest that the lens cannot be in the halo of the Galaxy, but is most likely in the SMC itself.
