Making use of the pronounced finite-source effects generated by the clump-giant source, we measure the Einstein radius $\\theta_\\rm E \\simeq 4.8\\,\\rm \\mu as$, and so infer a mass $M = 59\\,M_\\oplus (\\pi_\\rm{rel}/16 \\,\\rm \\mu as)^{-1}$, where $\\pi_\\rm{rel}$ is the lens-source relative parallax. We find no significant evidence for a host of this planetary mass object, though one could be present at sufficiently wide separation. If so, it would be detectable after about 10 years.
