We present center-surround application to James Webb Space Telescope (JWST), Near Infrared Imager and Slitless Spectrograph (NIRISS) observations of Io, Jupiter’s innermost moon. This project is part of the JWST Early Release Science program (ERS1373) on the Jovian system. Io is the most geologically active body in our solar system however the locations of tidal heating in the interior and temperature of Io’s magma leading to the volcanic eruptions are not well constrained. NIRISS's Aperture Masking Interferometry (AMI) mode that utilizes a 7-hole non-redundant mask (NRM) in its pupil plane provides high-resolution imaging with moderate contrast, and better astrometric accuracy over a wide field of view than conventional imaging. We present interferometric observations of Io from ERS1373 using NRM and filter F430M that is well matched to the emission from Io’s 500 K to 2000 K lava flows. NIRISS' AMI mode is the first time NRM is used in space. Convolution of Io images with center-surround kernel is used to emphasize fine structure on Io's disk. This convolved image can then be used as a 'prior' to reconstruct images from interferometric data of Io, thus helping to provide new measurements of the global distribution of vulcanism on Io and improving constraints on the locations of tidal heating in the interior.
