Unpublished WeCAPP data allows us to confirm
OAB-N2, previously reported only as a viable candidate, as a
well constrained pixel lensing event. The updated photometry
enables a detailed analysis in the event parameter space
including the effects due to finite source size. The combined
results of these analyses allow us to put a strong lower limit
on the lens proper motion. This outcome favors the MACHO lensing
hypothesis over self lensing for this individual event.
