New JWST Discoveries on the Uranian System

Recent JWST NIRCam observations obtained through Program #6379 provide the deepest imaging yet of Uranus’s faint rings and small moons. The observations utilize the FULLP subarray of the short-wavelength detector, yielding a field of view spanning ~900,000 km, which is sufficient to cover the system out to Titania and to briefly capture Oberon near the corners of some images.  A full analysis of the dataset is ongoing, but the quality of the data is sufficient to reveal rings roughly an order of magnitude fainter than the known rings, and previously unseen moons with radii greater than 2 km. We will present the detailed results of our analysis of these images, including the orbital and photometric properties of any newly discovered moons.
