We present the first resolved near infrared imagery of the transition diskOph IRS 48 (WLY 2-48), which was recently observed with ALMA to have a stronglyasymmetric sub-millimeter flux distribution. H-band polarized intensity imagesshow a $\sim$60AU radius scattered light cavity with two pronounced arcs ofemission, one from Northeast to Southeast and one smaller, fainter and moredistant arc in the Northwest. K-band scattered light imagery reveals a similarmorphology, but with a clear third arc along the Southwestern rim of the diskcavity. This arc meets the Northwestern arc at nearly a right angle, revealingthe presence of a spiral arm or local surface brightness deficit in the disk,and explaining the East-West brightness asymmetry in the H-band data. We alsopresent 0.8-5.4$\mu$m IRTF SpeX spectra of this object, which allow us toconstrain the spectral class to A0$\pm$1 and measure a low mass accretion rateof 10$^{-8.5}$M$_{\odot}$/yr, both consistent with previous estimates. Weinvestigate a variety of reddening laws in order to fit the mutliwavelength SEDof Oph IRS 48 and find a best fit consistent with a younger, higher luminositystar than previous estimates.
