Abstract

Of the large number of microlensing events detected towards the galactic bulge, there has been at least one clear case of a binary lens system, the OGLE 7 event. If this event had been observed simultaneously from three 1 m class ground-based telescopes during its second caustic crossing, an identification of the lens as a bulge or disk object and a determination of the orientation of the lens velocity on the sky could have been made.
