Astrometry in the Uranian system of satellites

The predicted occultation between the satellites Miranda(UV) and Oberon(UIV) was observed on July 30, 2007 using SpeX/IRTF system and CODAM‐Paris Observatory facility. Data analysis reveals that the predicted magnitude drop for this phenomenon was overestimated and we establish an upper limit of $0m.05$ for the phenomenon, perhaps due to a non‐lambertian limb scattering. The astrometry obtained from this run reveals good agreement with the LA06 numerical model.
