We have spatially resolved the debris disk around the A5 star HD 32297 in scattered light using Keck NIRC2 coronagraphic imaging with adaptive optics in the H and K bands. We used angular differential imaging to suppress the stellar PSF and reveal the nearly edge-on disk. Our investigation into the inner structure of the disk seeks to characterize the previously reported brightness asymmetry. This is a key region given the links between extrasolar planets and circumstellar debris disks, and our study benefits from the high angular resolution of Keck adaptive optics. Additionally, our measurement of the disk color can help to constrain the nature and distribution of grains present in the system.
